--
-- This operation allows you to perform batch reads or writes on data
-- stored in DynamoDB, using PartiQL. Each read statement in a
-- @BatchExecuteStatement@ must specify an equality condition on all key
-- attributes. This enforces that each @SELECT@ statement in a batch
-- returns at most a single item.
--
-- The entire batch must consist of either read statements or write
-- statements, you cannot mix both in one batch.
--
-- A HTTP 200 response does not mean that all statements in the
-- BatchExecuteStatement succeeded. Error details for individual statements
-- can be found under the
-- <https://docs.aws.amazon.com/amazondynamodb/latest/APIReference/API_BatchStatementResponse.html#DDB-Type-BatchStatementResponse-Error Error>
-- field of the @BatchStatementResponse@ for each statement.
