BatchDeleteAttributes
Description
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
BatchDeleteAttributesoperation
