Task operations like Start, Complete or Claim can be noticeably slower when KIE Server API or the UserTaskService is used. This known issue will be fixed in a patch release. The fix will restore the performance of these operations to the previous state.

Description
The getTaskInstanceById query was changed in JBPM-8116. A join with another table, called NodeInstanceLog, is needed now to retrieve slaDueDate and slaCompliance information.
The results are:
| Operation | Before (without |
After (with |
Difference |
|---|---|---|---|
| Task Start | 17.0104 ms | 26.7346 ms | +57% |
| Task Complete | 39.3893 ms | 49.5466 ms | +26% |
| Task Claim | 16.2741 ms | 25.9019 ms | +59% |
The introduction of the join was accepted in the PR but we should probably at least include this in the release notes that we are aware of it. If it is decided that this decrease is not acceptable, we might try to implement it differently.
