ObjectQueue has been updated to address performance issues. The following objects have been updated:
dbo.ObjectQueue - Specialized indexes for CurrentQueue and CallbackQueue usage
ObjectQueue/PopItem - Optimized to reduce/eliminate deadlocks
ObjectQueue contention was causing deadlocks for:
Callback processing
CurrentQueue processing
which resulted in stalled workflows and overall database contention.
Please ensure the above updates are deployed together to avoid any performance issues.
