> Most of the methods in the group coordinator interface use requests that match the corresponding request in the Kafka protocol. But `fetchOffsets` API currently takes only a single group from a batched request and is invoked multiple times when the request is batched. Since the batched version of the API is used by Admin client, it will be good to optimize request processing by sending the batched request to the group coordinator instead. For older versions of the API, we can pass a single group in the batch.
