Manikumar resolved KAFKA-845. ----------------------------- Resolution: Auto Closed Closing inactive issue. > Re-implement shallow iteration on 0.8.1 > --------------------------------------- > > Key: KAFKA-845 > URL: https://issues.apache.org/jira/browse/KAFKA-845 > Project: Kafka > Issue Type: Improvement > Components: core > Affects Versions: 0.8.1 > Reporter: Maxime Brugidou > > After KAFKA-732 we decided to not support the shallow iteration feature to > speed up the 0.8 release. > This severely impacts the performance for heavy mirroring between clusters. > The MirrorMaker needs to decompress/recompress the data which actually triple > the CPU compression cost in the data flow (initial compression + 2x > compression for mirroring). > It would be great to discuss a solution to re-implement the feature correctly. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
