[jira] [Created] (IOTDB-1938) compare timeseries when loading tsfile

yusicheng created IOTDB-1938:
--------------------------------

             Summary: compare timeseries when loading tsfile
                 Key: IOTDB-1938
                 URL: https://issues.apache.org/jira/browse/IOTDB-1938
             Project: Apache IoTDB
          Issue Type: Bug
          Components: Core/Server
    Affects Versions: 0.12.2, master branch
            Reporter: yusicheng
            Assignee: yusicheng


Now:
  Every device's start time and end time will be compared to determine which folder(seq/unseq) the loading tsfile belongs to.
  But sometimes, a device which two tsfiles both have may have different measurements, while the device has the same start time and end time, and the loading tsfile will be loaded in unseq folder.

Should:
  We should consider two tsfiles is not overlap with each other, because two tsfiles have different timeseries. Obviously, the time of compare every timeseries in loading tsfile is much less than the time of unseq compaction.
