[jira] [Updated] (QPID-8385) [Broker-J] Improve performance of
operation to dequeue queue entries on message expiration or triggering ring
policy
[ https://issues.apache.org/jira/browse/QPID-8385?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Alex Rudyy updated QPID-8385:
-----------------------------
Description:
AutoCommitTransaction is used to dequeue entries on message expiration or breaching ring policy threshold. As result, the dequeueing operation for persistent queue entry blocks until queue entry record is removed from the store and the underlying store transaction is synced to disk. The sequential removal of multiple entries can results in unnecessary delays due to syncing disk on every dequeue.
The broker performance for the corner cases described above can be significantly improved by using asynchronous transactions in dequeue operations.
Asynchronous transaction does not wait for the store dequeue transaction to sync to disk. As result, the performance of removal unneeded queue entries can increase.
