zk.read.num.retries — Kafka Producer Configuration

The producer using the zookeeper software load balancer maintains a ZK cache that gets updated by the zookeeper watcher listeners. During some events like a broker bounce, the producer ZK cache can get into an inconsistent state, for a small time period.

Description

The producer using the zookeeper software load balancer maintains a ZK cache that gets updated by the zookeeper watcher listeners. During some events like a broker bounce, the producer ZK cache can get into an inconsistent state, for a small time period. In this time period, it could end up picking a broker partition that is unavailable. When this happens, the ZK cache needs to be updated. This parameter specifies the number of times the producer attempts to refresh this ZK cache.
