> I can provide steps to reproduce this issue.  The state change logger needs
> to be guarded (to check if trace logging is turned on or not).
> The delete topic patch significantly increased the amount of logging that we
> do both on the controller. This results in higher latencies in state
> transitions and can slow down the controller (as well as the broker).  This
> slow-down was how we ran into KAFKA-1342.
