For example, with a hash type primary key, you only need to provide the hash attribute. For a hash-and-range type primary key, you must provide both, the hash attribute and the range attribute.See:  smart constructor.L Represents a single element of a key schema. A key schema specifies the attributes that make up the primary key of a table, or the key attributes of an index.A KeySchemaElementy represents exactly one attribute of the primary key. For example, a hash type primary key would be represented by one KeySchemaElement7. A hash-and-range type primary key would require one KeySchemaElement& for the hash attribute, and another KeySchemaElement for the range attribute.See:  smart constructor.MRInformation about item collections, if any, that were affected by the operation.

This condition can be used with  DeleteItem, PutItem or  UpdateItemu operations; if the comparison evaluates to true, the operation succeeds; if not, the operation fails. You can use ExpectedAttributeValue in one of two different ways:Use AttributeValueListI to specify one or more values to compare against an attribute. Use ComparisonOperator to specify how you want to perform the comparison. If the comparison evaluates to true, then the conditional operation succeeds.Use Valued to specify a value that DynamoDB will compare against an attribute. If the values match, then ExpectedAttributeValueb evaluates to true and the conditional operation succeeds. Optionally, you can also set Exists$ to false, indicating that you do not expect to find the attribute value in the table. In this case, the conditional operation succeeds only if the comparison evaluates to false.Value and Exists are incompatible with AttributeValueList and ComparisonOperatorP.

Instead, you will need to delete the item, and then use PutItem+ to create a new item with new attributes.Attribute values cannot be null; string and binary type attributes must have lengths greater than zero; and set type attributes must not be empty. Requests with empty values will be rejected with a ValidationException exception.See: i smart constructor.YVRepresents the data for an attribute. You can set one, and only one, of the elements.$Each attribute in an item is a name-value pair. An attribute can be single-valued or multi-valued set. For example, a book item can have title and authors attributes. Each book has one title but can have many authors.

Valid values are PUT (default), DELETE, and ADDY. The behavior depends on whether the specified primary key already exists in the table.If an item with the specified Key is found in the table:PUTs - Adds the specified attribute to the item. If the attribute already exists, it is replaced by the new value.DELETE - If no value is specified, the attribute and its value are removed from the item. The data type of the specified value must match the existing value's data type.If a set of values is specified, then those values are subtracted from the old set. For example, if the attribute value was the set '[a,b,c]' and the DELETEo action specified '[a,c]', then the final attribute value would be '[b]'. Specifying an empty set is an error.ADD - If the attribute does not already exist, then the attribute and its values are added to the item. If the attribute does exist, then the behavior of ADD0 depends on the data type of the attribute:.If the existing attribute is a number, and if Value! is also a number, then the Value< is mathematically added to the existing attribute. If ValueN is a negative number, then it is subtracted from the existing attribute. If you use ADD to increment or decrement a number value for an item that doesn't exist before the update, DynamoDB uses 0 as the initial value.In addition, if you use ADD to update an existing item, and intend to increment or decrement an attribute value which does not yet exist, DynamoDB uses '0't as the initial value. For example, suppose that the item you want to update does not yet have an attribute named  itemcount, but you decide to ADD the number '3'^ to this attribute anyway, even though it currently does not exist. DynamoDB will create the  itemcount& attribute, set its initial value to '0', and finally add '3'" to it. The result will be a new  itemcount) attribute in the item, with a value of '3'./If the existing data type is a set, and if the Value is also a set, then the Value/ is added to the existing set. (This is a setn operation, not mathematical addition.) For example, if the attribute value was the set '[1,2]', and the ADD action specified '[3]', then the final attribute value would be '[1,2,3]'. An error occurs if an Add action is specified for a set attribute and the attribute type specified does not match the existing set type.sBoth sets must have the same primitive data type. For example, if the existing data type is a set of strings, the ValueV must also be a set of strings. The same holds true for number sets and binary sets.gThis action is only valid for an existing attribute whose data type is number or is a set. Do not use ADD for any other data types.If no item with the specified Key is found:PUT` - DynamoDB creates a new item with the specified primary key, and then adds the attribute.DELETE4 - Nothing happens; there is no attribute to delete.ADD - DynamoDB creates an item with the supplied primary key and number (or set of numbers) for the attribute value.

DynamoDB determines capacity units consumed based on item size, not on the amount of data that is returned to an application.You cannot use both AttributesToGet and Select together in a Query request, unless the value for Select is SPECIFIC_ATTRIBUTES+. (This usage is equivalent to specifying AttributesToGet without any value for Select.)If you query a local secondary index and request only attributes that are projected into that index, the operation will read only the index and not the table. If any of the requested attributes are not projected into the local secondary index, DynamoDB will fetch each of these attributes from the parent table.

For type String, the results are returned in order of ASCII character code values. For type Binary, DynamoDB treats each byte of the binary data as unsigned.If ScanIndexForward is trueU, DynamoDB returns the results in order, by range key. This is the default behavior.If ScanIndexForward is falsel, DynamoDB sorts the results in descending order by range key, and then returns the results to the client. The maximum number of items to evaluate (not necessarily the number of matching items). If DynamoDB processes the number of items up to the limit while processing the results, it stops the operation and returns the matching values up to that point, and a key in LastEvaluatedKey to apply in a subsequent operation, so that you can pick up where you left off. Also, if the processed data set size exceeds 1 MB before DynamoDB reaches this limit, it stops the operation and returns the matching values up to the limit, and a key in LastEvaluatedKey\ to apply in a subsequent operation to continue the operation.

You can retrieve all item attributes, specific item attributes, the count of matching items, or in the case of an index, some or all of the attributes projected into the index.ALL_ATTRIBUTES - Returns all of the item attributes from the specified table or index. If you query a local secondary index, then for each matching item in the index DynamoDB will fetch the entire item from the parent table. If the index is configured to project all item attributes, then all of the data can be obtained from the local secondary index, and no fetching is required.ALL_PROJECTED_ATTRIBUTES - Allowed only when querying an index. Retrieves all attributes that have been projected into the index. If the index is configured to project all attributes, this return value is equivalent to specifying ALL_ATTRIBUTES.COUNTX - Returns the number of matching items, rather than the matching items themselves.SPECIFIC_ATTRIBUTES. - Returns only the attributes listed in AttributesToGet5. This return value is equivalent to specifying AttributesToGet" without specifying any value for Select.If you query a local secondary index and request only attributes that are projected into that index, the operation will read only the index and not the table. If any of the requested attributes are not projected into the local secondary index, DynamoDB will fetch each of these attributes from the parent table. This extra fetching incurs additional throughput cost and latency.If you query a global secondary index, you can only request attributes that are projected into the index. Global secondary index queries cannot fetch attributes from the parent table. If neither Select nor AttributesToGet& are specified, DynamoDB defaults to ALL_ATTRIBUTES when accessing a table, and ALL_PROJECTED_ATTRIBUTES/ when accessing an index. You cannot use both Select and AttributesToGet5 together in a single request, unless the value for Select is SPECIFIC_ATTRIBUTES+. (This usage is equivalent to specifying AttributesToGet without any value for Select.)If you use the ProjectionExpression parameter, then the value for Select can only be SPECIFIC_ATTRIBUTES. Any other value for Select will return an error.PThe condition that specifies the key value(s) for items to be retrieved by the Query action.The condition must perform an equality test on a single hash key value. The condition can also perform one of several comparison tests on a single range key value. Query can use KeyConditionExpression to retrieve one item with a given hash and range key value, or several items that have the same hash key value but different range key values.WThe hash key equality test is required, and must be specified in the following format:hashAttributeName =  ':hashval'NIf you also want to provide a range key condition, it must be combined using ANDB with the hash key condition. Following is an example, using the =' comparison operator for the range key:hashAttributeName =  ':hashval' AND rangeAttributeName =  ':rangeval'=Valid comparisons for the range key condition are as follows:rangeAttributeName =  ':rangeval'* - true if the range key is equal to  ':rangeval'.rangeAttributeName <  ':rangeval'+ - true if the range key is less than  ':rangeval'.rangeAttributeName <=  ':rangeval'7 - true if the range key is less than or equal to  ':rangeval'.rangeAttributeName >  ':rangeval'. - true if the range key is greater than  ':rangeval'.rangeAttributeName >=  ':rangeval': - true if the range key is greater than or equal to  ':rangeval'.rangeAttributeName BETWEEN  ':rangeval1' AND  ':rangeval2': - true if the range key is greater than or equal to  ':rangeval1'!, and less than or equal to  ':rangeval2'. begins_with (rangeAttributeName,  ':rangeval') - true if the range key begins with a particular operand. (You cannot use this function with a range key that is of type Number.) Note that the function name  begins_with is case-sensitive.Use the ExpressionAttributeValues& parameter to replace tokens such as  ':hashval' and  ':rangeval' with actual values at runtime.You can optionally use the ExpressionAttributeNames parameter to replace the names of the hash and range attributes with placeholder tokens. This option might be necessary if an attribute name conflicts with a DynamoDB reserved word. For example, the following KeyConditionExpression# parameter causes an error because Size is a reserved word:'Size = :myval'2To work around this, define a placeholder (such a '#S'#) to represent the attribute name Size. KeyConditionExpression then is as follows: '#S = :myval'#For a list of reserved words, see  Rhttp://docs.aws.amazon.com/amazondynamodb/latest/developerguide/ReservedWords.htmlReserved Words in the Amazon DynamoDB Developer Guide.For more information on ExpressionAttributeNames and ExpressionAttributeValues, see  [http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/ExpressionPlaceholders.html1Using Placeholders for Attribute Names and Values in the Amazon DynamoDB Developer Guide.KeyConditionExpression replaces the legacy  KeyConditions parameter.UThis is a legacy parameter, for backward compatibility. New applications should use FilterExpression instead. Do not combine legacy parameters and expression parameters in a single API call; otherwise, DynamoDB will return a ValidationException exception.3A logical operator to apply to the conditions in a  QueryFilter map:ANDY - If all of the conditions evaluate to true, then the entire map evaluates to true.-b - If at least one of the conditions evaluate to true, then the entire map evaluates to true.

UThis is a legacy parameter, for backward compatibility. New applications should use FilterExpression instead. Do not combine legacy parameters and expression parameters in a single API call; otherwise, DynamoDB will return a ValidationException exception.QA condition that evaluates the scan results and returns only the desired values.?This parameter does not support attributes of type List or Map..If you specify more than one condition in the  ScanFilter map, then by default all of the conditions must evaluate to true. In other words, the conditions are ANDed together. (You can use the ConditionalOperator parameter to OR the conditions instead. If you do this, then at least one of the conditions must evaluate to true, rather than all of them.)Each  ScanFilterM element consists of an attribute name to compare, along with the following:AttributeValueList - One or more values to evaluate against the supplied attribute. The number of values in the list depends on the operator specified in ComparisonOperator ./For type Number, value comparisons are numeric.xString value comparisons for greater than, equals, or less than are based on ASCII character code values. For example, a is greater than A, and a is greater than ". For a list of code values, see  =http://en.wikipedia.org/wiki/ASCII#ASCII_printable_characters.eFor Binary, DynamoDB treats each byte of the binary data as unsigned when it compares binary values.7For information on specifying data types in JSON, see  Ohttp://docs.aws.amazon.com/amazondynamodb/latest/developerguide/DataFormat.htmlJSON Data Format in the Amazon DynamoDB Developer Guide.ComparisonOperatorb - A comparator for evaluating attributes. For example, equals, greater than, less than, etc.1The following comparison operators are available:f'EQ | NE | LE | LT | GE | GT | NOT_NULL | NULL | CONTAINS | NOT_CONTAINS | BEGINS_WITH | IN | BETWEEN'<For complete descriptions of all comparison operators, see  Phttp://docs.aws.amazon.com/amazondynamodb/latest/APIReference/API_Condition.html Condition. UThis is a legacy parameter, for backward compatibility. New applications should use ProjectionExpression instead. Do not combine legacy parameters and expression parameters in a single API call; otherwise, DynamoDB will return a ValidationException exception.This parameter allows you to retrieve attributes of type List or Map; however, it cannot retrieve individual elements within a List or a Map.The names of one or more attributes to retrieve. If no attribute names are provided, then all attributes will be returned. If any of the requested attributes are not found, they will not appear in the result. Note that AttributesToGet has no effect on provisioned throughput consumption. DynamoDB determines capacity units consumed based on item size, not on the amount of data that is returned to an application. For a parallel Scan request,  TotalSegments9 represents the total number of segments into which the Scan* operation will be divided. The value of  TotalSegments corresponds to the number of application workers that will perform the parallel scan. For example, if you want to use four application threads to scan a table or an index, specify a  TotalSegments value of 4.The value for  TotalSegmentsZ must be greater than or equal to 1, and less than or equal to 1000000. If you specify a  TotalSegments value of 1, the Scan3 operation will be sequential rather than parallel.If you specify  TotalSegments, you must also specify Segment. rOne or more substitution tokens for attribute names in an expression. The following are some use cases for using ExpressionAttributeNames:OTo access an attribute whose name conflicts with a DynamoDB reserved word.]To create a placeholder for repeating occurrences of an attribute name in an expression.cTo prevent special characters in an attribute name from being misinterpreted in an expression.Use the #r character in an expression to dereference an attribute name. For example, consider the following attribute name: PercentileThe name of this attribute conflicts with a reserved word, so it cannot be used directly in an expression. (For the complete list of reserved words, see  Rhttp://docs.aws.amazon.com/amazondynamodb/latest/developerguide/ReservedWords.htmlReserved Words in the Amazon DynamoDB Developer Guide=). To work around this, you could specify the following for ExpressionAttributeNames:'{"#P":"Percentile"}'KYou could then use this substitution in an expression, as in this example: '#P = :val'Tokens that begin with the :f character are /expression attribute values/, which are placeholders for the actual value at runtime.9For more information on expression attribute names, see  hhttp://docs.aws.amazon.com/amazondynamodb/latest/developerguide/Expressions.AccessingItemAttributes.htmlAccessing Item Attributes in the Amazon DynamoDB Developer Guide. BA string that contains conditions that DynamoDB applies after the ScanT operation, but before the data is returned to you. Items that do not satisfy the FilterExpression criteria are not returned.A FilterExpression is applied after the items have already been read; the process of filtering does not consume any additional read capacity units.For more information, see  bhttp://docs.aws.amazon.com/amazondynamodb/latest/developerguide/QueryAndScan.html#FilteringResultsFilter Expressions in the Amazon DynamoDB Developer Guide.FilterExpression replaces the legacy  ScanFilter and ConditionalOperator parameters.LA Boolean value that determines the read consistency model during the scan:If ConsistentRead is false, then ScanC will use eventually consistent reads. The data returned from Scan might not contain the results of other recently completed write operations (PutItem, UpdateItem or DeleteItem). The Scan- response might include some stale data.If ConsistentRead is true, then Scane will use strongly consistent reads. All of the write operations that completed before the Scan- began are guaranteed to be contained in the Scan response.The default setting for ConsistentRead is false9, meaning that eventually consistent reads will be used.tStrongly consistent reads are not supported on global secondary indexes. If you scan a global secondary index with ConsistentRead" set to true, you will receive a ValidationException.<One or more values that can be substituted in an expression.Use the : (colon) character in an expression to dereference an attribute value. For example, suppose that you wanted to check whether the value of the  ProductStatus$ attribute was one of the following:('Available | Backordered | Discontinued' You would first need to specify ExpressionAttributeValues as follows:['{ ":avail":{"S":"Available"}, ":back":{"S":"Backordered"}, ":disc":{"S":"Discontinued"} }'?You could then use these values in an expression, such as this:)'ProductStatus IN (:avail, :back, :disc)':For more information on expression attribute values, see  ehttp://docs.aws.amazon.com/amazondynamodb/latest/developerguide/Expressions.SpecifyingConditions.htmlSpecifying Conditions in the Amazon DynamoDB Developer Guide.Undocumented member. The maximum number of items to evaluate (not necessarily the number of matching items). If DynamoDB processes the number of items up to the limit while processing the results, it stops the operation and returns the matching values up to that point, and a key in LastEvaluatedKey to apply in a subsequent operation, so that you can pick up where you left off. Also, if the processed data set size exceeds 1 MB before DynamoDB reaches this limit, it stops the operation and returns the matching values up to the limit, and a key in LastEvaluatedKey\ to apply in a subsequent operation to continue the operation.

You can retrieve all item attributes, specific item attributes, or the count of matching items.ALL_ATTRIBUTES& - Returns all of the item attributes.COUNTX - Returns the number of matching items, rather than the matching items themselves.SPECIFIC_ATTRIBUTES. - Returns only the attributes listed in AttributesToGet5. This return value is equivalent to specifying AttributesToGet" without specifying any value for Select. If neither Select nor AttributesToGet& are specified, DynamoDB defaults to ALL_ATTRIBUTES. You cannot use both AttributesToGet and Select4 together in a single request, unless the value for Select is SPECIFIC_ATTRIBUTES+. (This usage is equivalent to specifying AttributesToGet without any value for Select.)For a parallel Scan request, SegmentJ identifies an individual segment to be scanned by an application worker.Segment IDs are zero-based, so the first segment is always 0. For example, if you want to use four application threads to scan a table or an index, then the first thread specifies a Segment7 value of 0, the second thread specifies 1, and so on. The value of LastEvaluatedKey returned from a parallel Scan request must be used as ExclusiveStartKey+ with the same segment ID in a subsequent Scan operation.The value for SegmentK must be greater than or equal to 0, and less than the value provided for  TotalSegments.If you provide Segment, you must also provide  TotalSegments.UThis is a legacy parameter, for backward compatibility.

For  UpdateItem, the valid values are:NONE - If  ReturnValues+ is not specified, or if its value is NONEB, then nothing is returned. (This setting is the default for  ReturnValues.)ALL_OLD - If  UpdateItem[ overwrote an attribute name-value pair, then the content of the old item is returned. UPDATED_OLDE - The old versions of only the updated attributes are returned.ALL_NEWJ - All of the attributes of the new version of the item are returned. UPDATED_NEWE - The new versions of only the updated attributes are returned.kAn expression that defines one or more attributes to be updated, the action to be performed on them, and new value(s) for them..The following action values are available for UpdateExpression.SET - Adds one or more attributes and values to an item. If any of these attribute already exist, they are replaced by the new values. You can also use SETj to add or subtract from an attribute that is of type Number. For example: 'SET myNum = myNum + :val'SET" supports the following functions:m'if_not_exists (path, operand)' - if the item does not contain an attribute at the specified path, then  if_not_exists evaluates to operand; otherwise, it evaluates to path. You can use this function to avoid overwriting an attribute that may already be present in the item.'list_append (operand, operand)' - evaluates to a list with a new element added to it. You can append the new element to the start or the end of the list by reversing the order of the operands.(These function names are case-sensitive.REMOVE/ - Removes one or more attributes from an item.ADD - Adds the specified value to the item, if the attribute does not already exist. If the attribute does exist, then the behavior of ADD+ depends on the data type of the attribute:.If the existing attribute is a number, and if Value is also a number, then Value< is mathematically added to the existing attribute. If ValueN is a negative number, then it is subtracted from the existing attribute. If you use ADDk to increment or decrement a number value for an item that doesn't exist before the update, DynamoDB uses '0' as the initial value.Similarly, if you use ADDy for an existing item to increment or decrement an attribute value that doesn't exist before the update, DynamoDB uses '0'o as the initial value. For example, suppose that the item you want to update doesn't have an attribute named  itemcount, but you decide to ADD the number '3'5 to this attribute anyway. DynamoDB will create the  itemcount% attribute, set its initial value to '0', and finally add '3'! to it. The result will be a new  itemcount) attribute in the item, with a value of '3'.*If the existing data type is a set and if Value is also a set, then Valued is added to the existing set. For example, if the attribute value is the set '[1,2]', and the ADDf action specified '[3]', then the final attribute value is '[1,2,3]'. An error occurs if an ADDy action is specified for a set attribute and the attribute type specified does not match the existing set type.sBoth sets must have the same primitive data type. For example, if the existing data type is a set of strings, the Value must also be a set of strings.The ADD? action only supports Number and set data types. In addition, ADDB can only be used on top-level attributes, not nested attributes.DELETE! - Deletes an element from a set.If a set of values is specified, then those values are subtracted from the old set. For example, if the attribute value was the set '[a,b,c]' and the DELETEi action specifies '[a,c]', then the final attribute value is '[b]'. Specifying an empty set is an error.The DELETE4 action only supports set data types. In addition, DELETEB can only be used on top-level attributes, not nested attributes.You can have many actions in a single expression, such as the following: 'SET a=:value1, b=:value2 DELETE :value3, :value4, :value5'1For more information on update expressions, see  Zhttp://docs.aws.amazon.com/amazondynamodb/latest/developerguide/Expressions.Modifying.htmlModifying Items and Attributes in the Amazon DynamoDB Developer Guide.UpdateExpression replaces the legacy AttributeUpdates parameter.l<One or more values that can be substituted in an expression.Use the : (colon) character in an expression to dereference an attribute value.

If you are updating an attribute that is an index key attribute for any indexes on that table, the attribute type must match the index key type defined in the AttributesDefinition( of the table description. You can use  UpdateItem" to update any nonkey attributes.Attribute values cannot be null. String and Binary type attributes must have lengths greater than zero. Set type attributes must not be empty. Requests with empty values will be rejected with a ValidationException exception.Each AttributeUpdatesL element consists of an attribute name to modify, along with the following:Value4 - The new value, if applicable, for this attribute.Action - A value that specifies how to perform the update. This action is only valid for an existing attribute whose data type is Number or is a set; do not use ADD for other data types.uIf an item with the specified primary key is found in the table, the following values perform the following actions:PUTs - Adds the specified attribute to the item. If the attribute already exists, it is replaced by the new value.DELETEJ - Removes the attribute and its value, if no value is specified for DELETEV. The data type of the specified value must match the existing value's data type.If a set of values is specified, then those values are subtracted from the old set. For example, if the attribute value was the set '[a,b,c]' and the DELETEj action specifies '[a,c]', then the final attribute value is '[b]'.

Expected' provides a conditional block for the  UpdateItem operation.Each element of Expected consists of an attribute name, a comparison operator, and one or more values. DynamoDB compares the attribute with the value(s) you supplied, using the comparison operator. For each Expected@ element, the result of the evaluation is either true or false.,If you specify more than one element in the Expected map, then by default all of the conditions must evaluate to true. In other words, the conditions are ANDed together. (You can use the ConditionalOperator parameter to OR the conditions instead. If you do this, then at least one of the conditions must evaluate to true, rather than all of them.)If the ExpectedV map evaluates to true, then the conditional operation succeeds; otherwise, it fails.Expected contains the following:AttributeValueList| - One or more values to evaluate against the supplied attribute. The number of values in the list depends on the ComparisonOperator being used./For type Number, value comparisons are numeric.xString value comparisons for greater than, equals, or less than are based on ASCII character code values. For example, a is greater than A, and a is greater than ". For a list of code values, see  =http://en.wikipedia.org/wiki/ASCII#ASCII_printable_characters.jFor type Binary, DynamoDB treats each byte of the binary data as unsigned when it compares binary values.ComparisonOperator6 - A comparator for evaluating attributes in the AttributeValueListO. When performing the comparison, DynamoDB uses strongly consistent reads.1The following comparison operators are available:f'EQ | NE | LE | LT | GE | GT | NOT_NULL | NULL | CONTAINS | NOT_CONTAINS | BEGINS_WITH | IN | BETWEEN';The following are descriptions of each comparison operator.  : Equal. ? is supported for all datatypes, including lists and maps.AttributeValueList can contain only one AttributeValuei element of type String, Number, Binary, String Set, Number Set, or Binary Set. If an item contains an AttributeValue element of a different type than the one provided in the request, the value does not match. For example, '{"S":"6"}' does not equal '{"N":"6"}'.

NOT_NULL? is supported for all datatypes, including lists and maps.jThis operator tests for the existence of an attribute, not its data type. If the data type of attribute "a&" is null, and you evaluate it using NOT_NULL, the result is a Boolean true(. This result is because the attribute "a0" exists; its data type is not relevant to the NOT_NULL comparison operator.NULL! : The attribute does not exist. NULL? is supported for all datatypes, including lists and maps.mThis operator tests for the nonexistence of an attribute, not its data type. If the data type of attribute "a&" is null, and you evaluate it using NULL, the result is a Boolean false!. This is because the attribute "a0" exists; its data type is not relevant to the NULL comparison operator.CONTAINS/ : Checks for a subsequence, or value in a set.AttributeValueList can contain only one AttributeValuer element of type String, Number, or Binary (not a set type). If the target attribute of the comparison is of type String, then the operator checks for a substring match. If the target attribute of the comparison is of type Binary, then the operator looks for a subsequence of the target that matches the input. If the target attribute of the comparison is a set ("SS", "NS", or "BS_"), then the operator evaluates to true if it finds an exact match with any member of the set.ECONTAINS is supported for lists: When evaluating "'a CONTAINS b'", "a" can be a list; however, "b%" cannot be a set, a map, or a list. NOT_CONTAINSL : Checks for absence of a subsequence, or absence of a value in a set.AttributeValueList can contain only one AttributeValue element of type String, Number, or Binary (not a set type). If the target attribute of the comparison is a String, then the operator checks for the absence of a substring match. If the target attribute of the comparison is Binary, then the operator checks for the absence of a subsequence of the target that matches the input. If the target attribute of the comparison is a set ("SS", "NS", or "BS/"), then the operator evaluates to true if it does not1 find an exact match with any member of the set.MNOT_CONTAINS is supported for lists: When evaluating "'a NOT CONTAINS b'", "a" can be a list; however, "b%" cannot be a set, a map, or a list.

The target attribute of the comparison must be of type String or Binary (not a Number or a set type).60 : Checks for matching elements within two sets.AttributeValueList can contain one or more AttributeValue elements of type String, Number, or Binary (not a set type). These attributes are compared against an existing set type attribute of an item. If any elements of the input set are present in the item attribute, the expression evaluates to true.BETWEEN] : Greater than or equal to the first value, and less than or equal to the second value.AttributeValueList must contain two AttributeValue elements of the same type, either String, Number, or Binary (not a set type). A target attribute matches if the target value is greater than, or equal to, the first element and less than, or equal to, the second element. If an item contains an AttributeValue element of a different type than the one provided in the request, the value does not match. For example, '{"S":"6"}' does not compare to '{"N":"6"}'.

For a list of code values, see  =http://en.wikipedia.org/wiki/ASCII#ASCII_printable_characters.jFor type Binary, DynamoDB treats each byte of the binary data as unsigned when it compares binary values.ComparisonOperator6 - A comparator for evaluating attributes in the AttributeValueListO. When performing the comparison, DynamoDB uses strongly consistent reads.1The following comparison operators are available:f'EQ | NE | LE | LT | GE | GT | NOT_NULL | NULL | CONTAINS | NOT_CONTAINS | BEGINS_WITH | IN | BETWEEN';The following are descriptions of each comparison operator.  : Equal. ? is supported for all datatypes, including lists and maps.AttributeValueList can contain only one AttributeValuei element of type String, Number, Binary, String Set, Number Set, or Binary Set. If an item contains an AttributeValue element of a different type than the one provided in the request, the value does not match. For example, '{"S":"6"}' does not equal '{"N":"6"}'. Also, '{"N":"6"}' does not equal '{"NS":["6", "2", "1"]}'.3 : Not equal. 3? is supported for all datatypes, including lists and maps.AttributeValueList can contain only one AttributeValuea of type String, Number, Binary, String Set, Number Set, or Binary Set.

NOT_NULL? is supported for all datatypes, including lists and maps.jThis operator tests for the existence of an attribute, not its data type. If the data type of attribute "a&" is null, and you evaluate it using NOT_NULL, the result is a Boolean true(. This result is because the attribute "a0" exists; its data type is not relevant to the NOT_NULL comparison operator.NULL! : The attribute does not exist. NULL? is supported for all datatypes, including lists and maps.mThis operator tests for the nonexistence of an attribute, not its data type. If the data type of attribute "a&" is null, and you evaluate it using NULL, the result is a Boolean false!. This is because the attribute "a0" exists; its data type is not relevant to the NULL comparison operator.CONTAINS/ : Checks for a subsequence, or value in a set.AttributeValueList can contain only one AttributeValuer element of type String, Number, or Binary (not a set type). If the target attribute of the comparison is of type String, then the operator checks for a substring match. If the target attribute of the comparison is of type Binary, then the operator looks for a subsequence of the target that matches the input. If the target attribute of the comparison is a set ("SS", "NS", or "BS_"), then the operator evaluates to true if it finds an exact match with any member of the set.ECONTAINS is supported for lists: When evaluating "'a CONTAINS b'", "a" can be a list; however, "b%" cannot be a set, a map, or a list. NOT_CONTAINSL : Checks for absence of a subsequence, or absence of a value in a set.AttributeValueList can contain only one AttributeValue element of type String, Number, or Binary (not a set type). If the target attribute of the comparison is a String, then the operator checks for the absence of a substring match. If the target attribute of the comparison is Binary, then the operator checks for the absence of a subsequence of the target that matches the input.

BEGINS_WITH : Checks for a prefix.AttributeValueList can contain only one AttributeValue of type String or Binary (not a Number or a set type). The target attribute of the comparison must be of type String or Binary (not a Number or a set type).60 : Checks for matching elements within two sets.AttributeValueList can contain one or more AttributeValue elements of type String, Number, or Binary (not a set type). These attributes are compared against an existing set type attribute of an item. If any elements of the input set are present in the item attribute, the expression evaluates to true.BETWEEN] : Greater than or equal to the first value, and less than or equal to the second value.AttributeValueList must contain two AttributeValue elements of the same type, either String, Number, or Binary (not a set type). A target attribute matches if the target value is greater than, or equal to, the first element and less than, or equal to, the second element. If an item contains an AttributeValue element of a different type than the one provided in the request, the value does not match. For example, '{"S":"6"}' does not compare to '{"N":"6"}'. Also, '{"N":"6"}' does not compare to '{"NS":["6", "2", "1"]}'For usage examples of AttributeValueList and ComparisonOperator, see  `http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/LegacyConditionalParameters.htmlLegacy Conditional Parameters in the Amazon DynamoDB Developer Guide.mFor backward compatibility with previous DynamoDB releases, the following parameters can be used instead of AttributeValueList and ComparisonOperator:Value5 - A value for DynamoDB to compare with an attribute.Existso - A Boolean value that causes DynamoDB to evaluate the value before attempting the conditional operation:If Exists is true, DynamoDB will check to see if that attribute value already exists in the table. If it is found, then the condition evaluates to true; otherwise the condition evaluate to false.If Exists is false6, DynamoDB assumes that the attribute value does not exist in the table. If in fact the value does not exist, then the assumption is valid and the condition evaluates to true. If the value is found, despite the assumption that it does not exist, the condition evaluates to false. Note that the default value for Exists is true.The Value and Exists# parameters are incompatible with AttributeValueList and ComparisonOperatorP.

This is the same as the hash key of the item.SizeEstimateRange - An estimate of item collection size, in gigabytes. This value is a two-element array containing a lower bound and an upper bound for the estimate. The estimate includes the size of all the items in the table, plus the size of all attributes projected into all of the local secondary indexes on that table. Use this estimate to measure whether a local secondary index is approaching its size limit.rThe estimate is subject to change over time; therefore, do not rely on the precision or accuracy of the estimate.Undocumented member.A map of attribute names to AttributeValue; objects, representing the item as it appeared before the  DeleteItem6 operation.

The following are some use cases for using ExpressionAttributeNames:OTo access an attribute whose name conflicts with a DynamoDB reserved word.]To create a placeholder for repeating occurrences of an attribute name in an expression.cTo prevent special characters in an attribute name from being misinterpreted in an expression.Use the #r character in an expression to dereference an attribute name. For example, consider the following attribute name: PercentileThe name of this attribute conflicts with a reserved word, so it cannot be used directly in an expression. (For the complete list of reserved words, see  Rhttp://docs.aws.amazon.com/amazondynamodb/latest/developerguide/ReservedWords.htmlReserved Words in the Amazon DynamoDB Developer Guide=). To work around this, you could specify the following for ExpressionAttributeNames:'{"#P":"Percentile"}'KYou could then use this substitution in an expression, as in this example: '#P = :val'Tokens that begin with the :f character are /expression attribute values/, which are placeholders for the actual value at runtime.9For more information on expression attribute names, see  hhttp://docs.aws.amazon.com/amazondynamodb/latest/developerguide/Expressions.AccessingItemAttributes.htmlAccessing Item Attributes in the Amazon DynamoDB Developer Guide.Use  ReturnValues\ if you want to get the item attributes as they appeared before they were updated with the PutItem request. For PutItem, the valid values are:NONE - If  ReturnValues+ is not specified, or if its value is NONEB, then nothing is returned. (This setting is the default for  ReturnValues.)ALL_OLD - If PutItem[ overwrote an attribute name-value pair, then the content of the old item is returned.1Other "Valid Values" are not relevant to PutItem.<One or more values that can be substituted in an expression.Use the : (colon) character in an expression to dereference an attribute value. For example, suppose that you wanted to check whether the value of the  ProductStatus$ attribute was one of the following:('Available | Backordered | Discontinued' You would first need to specify ExpressionAttributeValues as follows:['{ ":avail":{"S":"Available"}, ":back":{"S":"Backordered"}, ":disc":{"S":"Discontinued"} }'?You could then use these values in an expression, such as this:)'ProductStatus IN (:avail, :back, :disc)':For more information on expression attribute values, see  ehttp://docs.aws.amazon.com/amazondynamodb/latest/developerguide/Expressions.SpecifyingConditions.htmlSpecifying Conditions in the Amazon DynamoDB Developer Guide.Undocumented member.DDetermines whether item collection metrics are returned.

Expected' provides a conditional block for the PutItem operation.?This parameter does not support attributes of type List or Map.Each element of Expected consists of an attribute name, a comparison operator, and one or more values. DynamoDB compares the attribute with the value(s) you supplied, using the comparison operator. For each Expected@ element, the result of the evaluation is either true or false.,If you specify more than one element in the Expected map, then by default all of the conditions must evaluate to true. In other words, the conditions are ANDed together. (You can use the ConditionalOperator parameter to OR the conditions instead. If you do this, then at least one of the conditions must evaluate to true, rather than all of them.)If the ExpectedV map evaluates to true, then the conditional operation succeeds; otherwise, it fails.Expected contains the following:AttributeValueList| - One or more values to evaluate against the supplied attribute.
