----------------------------
Resolution: Fixed
> Add TsFileFilter in series reader to support distributed query
> --------------------------------------------------------------
>
> Key: IOTDB-505
> URL: https://issues.apache.org/jira/browse/IOTDB-505
> Project: Apache IoTDB
> Issue Type: Improvement
> Reporter: Tian Jiang
> Assignee: Tian Jiang
> Priority: Major
> Labels: distributed, filter, query
> Fix For: master branch
>
>
> In the distributed version of IoTDB, data of different data groups of a node
> is mixed together in an IoTDB instance. As a result, when querying the data
> of one group, data of other groups will also be queried, which is not desired.
> To resolve this, we need to add a TsFileFilter in series readers that will
> filter the TsFiles accordingly, so that the unwanted data will not be queried.
