/**
* Container for the parameters to the {@link com.amazonaws.services.simpledb.AmazonSimpleDB#batchDeleteAttributes(BatchDeleteAttributesRequest) BatchDeleteAttributes operation}.
*
* Performs multiple DeleteAttributes operations in a single call, which
* reduces round trips and latencies. This enables Amazon SimpleDB to
* optimize requests, which generally yields better throughput.
*
*
* NOTE: If you specify BatchDeleteAttributes without attributes
* or values, all the attributes for the item are deleted.
* BatchDeleteAttributes is an idempotent operation; running it multiple
* times on the same item or attribute doesn't result in an error. The
* BatchDeleteAttributes operation succeeds or fails in its entirety.
* There are no partial deletes. You can execute multiple
* BatchDeleteAttributes operations and other operations in parallel.
* However, large numbers of concurrent BatchDeleteAttributes calls can
* result in Service Unavailable (503) responses. This operation is
* vulnerable to exceeding the maximum URL size when making a REST
* request using the HTTP GET method. This operation does not support
* conditions using Expected.X.Name, Expected.X.Value, or
* Expected.X.Exists.
*
*
* The following limitations are enforced for this operation:
*
* - 1 MB request size
* - 25 item limit per BatchDeleteAttributes operation
*
*
