Description

Each creation and fetch of a RemoteSeriesReader requires one RPC and when there are many series involved in a query, the RPC overhead may increase significantly and slow down the whole query.

So it is reasonable to group RemoteSeriesReaders by the DataGroup they belong to, and send RPCs to create or fetch them in a batched manner.
