Network.AWS.SDB.PutAttributes
Description
The PutAttributes operation creates or replaces attributes in an item.
The client may specify new attributes using a combination of the
Name and Value parameters. The client
specifies the first attribute by the parameters 'Attribute.0.Name' and
'Attribute.0.Value', the second attribute by the parameters
'Attribute.1.Name' and 'Attribute.1.Value', and so on.
Attributes are uniquely identified in an item by their name/value
combination. For example, a single item can have the attributes
'{ "first_name", "first_value" }' and
'{ "first_name", second_value" }'. However, it cannot have two
attribute instances where both the Name and
Value are the same.
Optionally, the requestor can supply the Replace parameter for each
individual attribute. Setting this value to true causes the new
attribute value to replace the existing attribute value(s). For example,
if an item has the attributes '{ 'a', '1' }', '{ 'b', '2'}' and
'{ 'b', '3' }' and the requestor calls PutAttributes using the
attributes '{ 'b', '4' }' with the Replace parameter set to true,
the final attributes of the item are changed to '{ 'a', '1' }' and
'{ 'b', '4' }', which replaces the previous values of the 'b'
attribute with the new value.
You cannot specify an empty string as an attribute name.
Because Amazon SimpleDB makes multiple copies of client data and uses an eventual consistency update model, an immediate GetAttributes or Select operation (read) immediately after a PutAttributes or DeleteAttributes operation (write) might not return the updated data.
The following limitations are enforced for this operation:
- 256 total attribute name-value pairs per item
- One billion attributes per domain
- 10 GB of total user data storage per domain
See: AWS API Reference for PutAttributes.

Creating a Request
Arguments
| :: Text | |
| -> Text | |
| -> PutAttributes |
Creates a value of PutAttributes with the minimum fields required to make a request.
Use one of the following lenses to modify other fields as desired:
data PutAttributes Source
See: putAttributes smart constructor.
Instances
Request Lenses
paExpected :: Lens' PutAttributes (Maybe UpdateCondition) Source
The update condition which, if specified, determines whether the specified attributes will be updated or not. The update condition must be satisfied in order for this request to be processed and the attributes to be updated.
paDomainName :: Lens' PutAttributes Text Source
The name of the domain in which to perform the operation.
paItemName :: Lens' PutAttributes Text Source
The name of the item.
paAttributes :: Lens' PutAttributes [ReplaceableAttribute] Source
The list of attributes.
Destructuring the Response
putAttributesResponse :: PutAttributesResponse Source
Creates a value of PutAttributesResponse with the minimum fields required to make a request.
data PutAttributesResponse Source
See: putAttributesResponse smart constructor.
