> Currently FileRecords have a capability to slice records, however
> MemoryRecords don't have any. The slice API in MemoryRecords is needed to
> limit the bytes/records being sent to client from broker during `share
> fetch`. There can be a subset of records acquired by share fetch for the
> MemoryRecords batch hence MemoryRecords should be sliced to only send the
> batches which are acquired. If not sliced, then there can be unnecessary
> bytes transfer from the broker.
