GetAttributes

Description

Returns all of the attributes associated with the item. Optionally, the attributes returned can be limited to one or more specified attribute name parameters.

Amazon SimpleDB keeps multiple copies of each domain. When data is written or updated, all copies of the data are updated. However, it takes time for the update to propagate to all storage locations. The data will eventually be consistent, but an immediate read might not show the change. If eventually consistent reads are not acceptable for your application, use ConsistentRead. Although this operation might take longer than a standard read, it always returns the last updated value.

Note

If the item does not exist on the replica that was accessed for this operation, an empty set is returned.

If you specify GetAttributes without any attribute names, all the attributes for the item are returned.
