    • Release Note:
      Adds a section to the debug dump page listing current row locks held.

      Description

      We had to debug cases where some handlers are holding row locks for an extended time (and maybe leak) and other handlers are getting timeouts for obtaining row locks.

      We should add row lock information at the debug page at the RS UI to be able to live-debug such cases.
