[jira] [Created] (IOTDB-1117) [Distributed] Batched creation and fetch of RemoteSeriesReader

Tian Jiang created IOTDB-1117:
---------------------------------

             Summary: [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


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.
