Increase in Memory Cache After Upgrading to 1.1.0

*Hello All,We recently upgraded Kafka from 0.10.2 to 1.1.0 and we've seen an increase in the amount of cached memory used, resulting in the servers going into swap. Has anyone else seen this issue or would know why this would happen after the 1.1.0 upgrade? Thanks*

Upgrading Kafka from Version 0.10.2 to 1.0.0

Hello All, Is it easy to upgrade from Kafka version 0.10.2 to 1.0.0 or do I need to upgrade to version 0.11.0 first? Anything to expect? Thanks
