A Batch contains a collection of requests that are to be batched into a single API call.
A Batch contains a singleUnaryCallableobject, which will be used to make the API
call, and a list ofBatchedRequestIssuerobjects, which represent the individual requests
in the batch.
Additional batches can be merged into an existing batch using the <xref uid="com.google.api.gax.rpc.Batch.merge(com.google.api.gax.rpc.Batch<RequestT,ResponseT>)" data-throw-if-not-resolved="false">#merge(Batch)
method. Request objects are combined using aRequestBuilderinto a single request.
