[jira] [Created] (AMQ-5578) preallocate journal files

Gary Tully created AMQ-5578:
-------------------------------

             Summary: preallocate journal files
                 Key: AMQ-5578
                 URL: https://issues.apache.org/jira/browse/AMQ-5578
             Project: ActiveMQ
          Issue Type: Improvement
          Components: Message Store
    Affects Versions: 5.11.0
            Reporter: Gary Tully
            Assignee: Gary Tully
             Fix For: 5.12.0


Our journals are append only, however we use the size to track journal rollover on recovery and replay. We can improve performance if we never update the size on disk and preallocate on creation.
Rework journal logic to ensure size is never updated. This will allow the configuration option from https://issues.apache.org/jira/browse/AMQ-4947 to be the default.
