> [Distributed] Batched creation and fetch of RemoteSeriesReader
> --------------------------------------------------------------
>
> Key: IOTDB-1117
> URL: https://issues.apache.org/jira/browse/IOTDB-1117
> Project: Apache IoTDB
> Issue Type: Improvement
> Components: Cluster
> Reporter: Tian Jiang
> Priority: Major
> Labels: cluster, query
>
> 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.
