---------------------------------
Summary: Refactor Count TimeSeries Group By Level based on
SchemaReader
Key: IOTDB-5364
URL: https://issues.apache.org/jira/browse/IOTDB-5364
Project: Apache IoTDB
Issue Type: Improvement
Reporter: Yukun Zhou
Assignee: Yukun Zhou
Fix For: master branch
Currently, the LevelTimeSeriesCountOperator, serving feature "count timeseries
group by level", is implemented by invoking SchemaRegion interfaces directly,
which is unable to be interrupt and brings burden to SchemaRegion business
logic.
Since we want SchemaRegion to only provide the basic SchemaReader, we refactor
the implementation of LevelTimeSeriesCountOperator to extract the group by and
counting logic from SchemaRegion. Based on SchemaReader, it is more flexible to
interrupt the process and release resources.
