Hi Everyone, KIP-226 added support for dynamic update of broker configuration. In this KIP, we propose to extend the support to dynamic update of a group of new dynamic broker configs which will benefit the replication process.
The proposed support for new dynamic configs looks like failed.authentication.delay Connection close delay on failed authentication. fetch.max.bytes Maximum bytes expected for the entire fetch response. replica.fetch.backoff.ms The amount of time to sleep when fetch partition error occurs. replica.fetch.response.max.bytes Maximum bytes expected for the entire fetch response. replica.fetch.response.max.bytes Maximum bytes expected for the entire fetch response. replica.fetch.wait.max.ms Max wait time for each fetcher request issued by follower replicas. I’ve written a KIP about introducing exponential backoff for Kafka clients. Would appreciate any feedback on this.
