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.
