Assignee: Chao Wang
> Remove redundant sync meta leader in query process for cluster module
> ---------------------------------------------------------------------
>
> Key: IOTDB-1186
> URL: https://issues.apache.org/jira/browse/IOTDB-1186
> Project: Apache IoTDB
> Issue Type: Improvement
> Components: Core/Cluster
> Reporter: Xinyu Tan
> Assignee: Chao Wang
> Priority: Major
> Labels: pull-request-available
> Fix For: 0.12.0
>
>
> Currently, the coordinator will create one remoteSeriesReader for each
> timeseries if the timeseries belongs to other nodes, and the coordinator will
> try to perform a sync meta leader in each remoteSeriesReader's
> initManagedSeriesReader function, which cost a lot of network overhead.
> Actually, we can just sync meta leader once for one query.
