Guozhang Wang commented on KAFKA-1350: -------------------------------------- [~jjkoshy] Could you provide some more context? I thought the state change logging is guarded by log4j? > 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. -- This message was sent by Atlassian JIRA (v6.2#6252)
