    Description

      There are two code paths:

      1. Left side "MetaKVListner"
      2. Right side "PeriodicPushHandler"

      These both run in parallel and execute common logic of "handleBackfillRequestWithArgs". The yellow background are the separate threads/goroutines. If the periodicPushHandler wins and it ends up creating the backfill spec then it will be with the invalid VBs. Therefore the backfill pipeline exists with "no tasks to run"
