Br_ddl_full sometimes frozen

Please answer these questions before submitting your issue. Thanks!

  1. What did you do? run integration test br_ddl_full.

  2. What did you expect to see? The test passes in acceptable time duration.

  3. What did you see instead? On the restore process, the process bar frozen at 100% for a very long period(about 1hr.). And BR will repeat trying to call DownloadSST and try to ingest it. Eventually the test will pass, but restore a real strange size of file, alone with huge kv pair size: the restore result Some information may be useful:

  • The Download RPC was totally called about 1,660 times, and at the last SST file, scan regions shows that there are about 834 regions, and grep the log "scan regions", summing the count field, the answer is about 1,600.
  1. What version of BR and TiDB/TiKV/PD are you using? The branch Yujuncen/design-doc, but the current master may meet this problem so.
