codelipenghui opened a new pull request #4987: Trim deleted entries after recover cursor.
URL: https://github.com/apache/pulsar/pull/4987
 
 
   ### Motivation
   
   While broker recover a cursor, broker will dispatch all messages after the last mark delete entry, so is user has an early position not acked, broker will dispatch so many messages which is already acked by consumer.
   
   This pr will trim the acked messages while recover a cursor,  while the read position of the cursor is less than the upper of  LastIndividualDeletedRange, broker will trim the acked messages, otherwise not.
