Batch Request Support
The 'Data Service Hosting' feature provides capability to support batch requests for operations, which contain multiple parameter sets for a single request. When a data service is created with the batch request mode set, for all the in-only operations (operations which do not have any return value), a corresponding batch operation is also be automatically created. This batch operation takes in an array of parameters, compared to the single parameter list the non-batch operations require.
