[jira] [Created] (IOTDB-505) Add TsFileFilter in series reader to support distributed query

Tian Jiang created IOTDB-505:
--------------------------------

             Summary: 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


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.
