> Key: SYNCOPE-408
> URL: https://issues.apache.org/jira/browse/SYNCOPE-408
> Project: Syncope
> Issue Type: Improvement
> Components: core
> Affects Versions: 1.1.3
> Reporter: Guido Wimmel
> Assignee: Francesco Chicchiriccò
> Priority: Minor
> Fix For: 1.1.4, 1.2.0
>
> Attachments: indexes.xml.patch
>
>
> In our Syncope installation (1.1.3 on Tomcat/MySQL) we observed long
> execution times (>1s) for TaskDAO.findToExec(), which is called periodically
> from NotificationJob to determine which notifications should be sent.
> According to our analysis, this is due to the fact that TaskDAO.findToExec()
> performs a full scan on all entries of the task table with
> DTYPE="NotificationTask" (which could be a large number as all executed tasks
> are kept), although only very few tasks are selected (those with executed=0).
> Creating an index on task.executed solved this problem; attached is a
> corresponding patch against the branch 1.1.X.
