---------------------------------
Summary: Fix excessive state change logging
Key: KAFKA-1350
URL: https://issues.apache.org/jira/browse/KAFKA-1350
Project: Kafka
Issue Type: Bug
Affects Versions: 0.8.1
Reporter: Joel Koshy
Priority: Blocker
Fix For: 0.8.1.1
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.
