[GitHub] [iotdb] yschengzi opened a new pull request, #5740: [IOTDB-3049]Sync Sender loss data when restart IoTDB with data in working memtable

yschengzi opened a new pull request, #5740:
URL: https://github.com/apache/iotdb/pull/5740

   problem:
     Data loss happens when sender shutdowns with data in working memtable.
     When restarting IoTDB, WAL will restore all data in unsealed tsfile and close it, but this tsfile is not collected by running pipe.
   
   solution:
     add TsfFileSyncManager#collectRealTimeTsFile in DataRegion#callbackAfterUnsealedTsFileRecovered
     add TsFilePipeLogger#isHardlinkExist to judge if the tsfile hardlink is created or not, and simplified the process of collecting history tsfile.
     add IT
