[jira] [Commented] (SLING-5884) Deprecate JobManager methods which allow to manage the queue

["Stefan Egli (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SLING-5884?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16735886#comment-16735886 ] 

Stefan Egli commented on SLING-5884:
------------------------------------

h2. Variant B: allow opting out of job query support

Added an alternative solution ([here|https://github.com/stefan-egli/sling-org-apache-sling-event-api/tree/jobQueriesOptOut]) which, instead of deprecating job queries, introduces a config option (visualized via a new method {{QueueConfiguration.jobQueriesEnabled()}}).

The advantage of this variant is that nothing is deprecated, no _need_ for change, however users/admins of a system can choose to disable job queries on particular queues - thereby allowing the system to do optimizations as it doesn't have to support job queries.

Note that this will require a change in the implementation too (and the suggestion so far done is only in the API) - something which can be done once we agree upon which way (A or B) we go

> The {{JobManager}} contains methods which allow to manage the entries in the queue. Those methods such as {{o.a.s.e.j.JobManager#findJobs}} impose a heavy burden on the repository and can cause major runtime issues such as running the instance OOM.
> This issue tracks deprecating those API signatures.
