In a test by onurkaraman involving 3066 topics and 95895 partitions, Controller initialisation time spent on JSON parsing would be reduced from 37.1 seconds to 0.7 seconds by switching from the current JSON parser to Jackson. See the following JIRA comment for more details: https://issues.apache.org/jira/browse/KAFKA-5328?focusedCommentId=16027086 I tested that we only use Jackson methods introduced in 2.0 in the main codebase by compiling it with the older version locally. We use a constructor introduced in 2.4 in one test, but I didn't remove it as it seemed harmless. The reasoning for this is explained in the mailing list thread: http://search-hadoop.com/m/uyzND1FWbWw1qUbWe Finally, this PR only handles the parsing side. It would be good to use Jackson for serialising to JSON as well. I filed KAFKA-5631 for that.
