Justin Bertram updated ARTEMIS-4056:
------------------------------------
Fix Version/s: 2.27.0
> Optimize Paging Startup And Management operation
> ------------------------------------------------
>
> Key: ARTEMIS-4056
> URL: https://issues.apache.org/jira/browse/ARTEMIS-4056
> Project: ActiveMQ Artemis
> Issue Type: Improvement
> Reporter: Clebert Suconic
> Priority: Major
> Fix For: 2.27.0
>
> Time Spent: 1h 20m
> Remaining Estimate: 0h
>
> When there are a lot of queues paging, there are a few issues:
> - A few management operations are calling iterator(); and flushExecutors().
> What may put the server down.
> - Paging is eventually reading pages even when they are complete (to just
> discard their value, when there is a page-complete record).
> - Paging is calling checkDepage() during reload, what will eventually delay
> startup time.
> - The main one: getFirstMessage() on QueueControl is calling an iterator();
> Such iterator might put a lot of pressure in paging. (Imaging if you had 100
> queues in a paged address. all of them would be issuing the iterator().
> Tests are optimizations and the servers should just behave the same without
> them.
