preallocate journal files

    XMLWordPrintableJSON

Details

    Description

      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.
