--------------------------------
Summary: Add more levels of index in TsFileMetadata
Key: IOTDB-605
URL: https://issues.apache.org/jira/browse/IOTDB-605
Project: Apache IoTDB
Issue Type: Improvement
Reporter: Zesong Sun
Facing a scenario that one device has 300k measurements, when we read one time
series in a TsFile, we need to deserialize 300k TimeseriesMetadata, which costs
about 250ms (just for reading metadata of one tsfile). This may cause the query
much slow.
As this scenario is not rare, I think this should be optimized by adding more
indexes in TsFileMetadata.
