Description

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.
