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

Request
data PutAttributes Source
Request constructor
Arguments
| :: Text | |
| -> Text | |
| -> PutAttributes |
PutAttributes constructor.
The fields accessible through corresponding lenses are:
Request lenses
paAttributes :: Lens' PutAttributes [ReplaceableAttribute] Source
The list of attributes.
paDomainName :: Lens' PutAttributes Text Source
The name of the domain in which to perform the operation.
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.
paItemName :: Lens' PutAttributes Text Source
The name of the item.
Response
Response constructor
putAttributesResponse :: PutAttributesResponse Source
PutAttributesResponse constructor.
