[GitHub] [pulsar] poorbarcode commented on pull request #16679: [fix] [txn] [PIP-160] Avoid timing task burdens the ledger thread and leads to an avalanche

poorbarcode commented on PR #16679:
URL: https://github.com/apache/pulsar/pull/16679#issuecomment-1189434804

   > You said if the tasks are executed longer that interval, the queue starts building up until it explodes?
   
   Yes, I added more descriptions in `Motivation`.
   
   > I'm not sure I understand the nature of the context in this PR - would love a good brief on that - but could it be that executeWithFixedDelay will solve it, since it never starts the next task until the previous one is finished?
   
   This change can only avoid the task accumulation in TxnLogBufferedWriter caused by too many scheduled tasks but cannot improve the write performance of Managed Ledger. 
   
   I added more descriptions in `Motivation.`
   
   Thanks.
