…torical extractor (#12056) The data loss situation can be caused by the following operations: 1. PipeA: start historical data extraction with flush 2. Data insertion 3. PipeB: start realtime data extraction 4. PipeB: start historical data extraction without flush 5. Data inserted in the step2 is not captured by PipeB, and if its tsfile epoch's state is USING_TABLET, the tsfile event will be ignored, which will cause the data loss in the tsfile epoch. --------- Co-authored-by: Steve Yurong Su <[email protected]>
