jerrypeng opened a new pull request #5243: Bug in Message Deduplication that may cause incorrect client/broker interaction
URL: https://github.com/apache/pulsar/pull/5243
 
 
   
   
   ### Motivation
   
   Partially fixes #5218 
   
   Will be making subsequent PRs to fix issues with handling BK write failures
   
   ### Modifications
   
   The fix is two-fold:
   
   Double check the pending messages and return error to producer when the dup status is uncertain (eg. message is still pending)
   Sync back the lastPushed map with the lastStored map after the failures
