Zesong Sun created IOTDB-631:
--------------------------------

             Summary: Using new TsFile MetadataIndex to optimize query and cache
                 Key: IOTDB-631
                 URL: https://issues.apache.org/jira/browse/IOTDB-631
             Project: Apache IoTDB
          Issue Type: Improvement
            Reporter: Zesong Sun
            Assignee: Zesong Sun


As the new TsFile MetadataIndex is designed, we could do more optimization for querying process and TimeseriesMetadata Cache.

* provide a new List<TimeseriesMetadata> readTimeseriesMetadata(String device, Set<String> measurements) interface to get more sensors' TimeseriesMetadata and reduce IO.
