--------------------------------------
Summary: StreamsKafkaClient should not use
StreamsConfig.POLL_MS_CONFIG
Key: KAFKA-5464
URL: https://issues.apache.org/jira/browse/KAFKA-5464
Project: Kafka
Issue Type: Bug
Components: streams
Affects Versions: 0.10.2.1, 0.11.0.0
Reporter: Matthias J. Sax
Assignee: Matthias J. Sax
In {{StreamsKafkaClient}} we use an {{NetworkClient}} internally and call
{{poll}} using {{StreamsConfig.POLL_MS_CONFIG}} as timeout.
However, {{StreamsConfig.POLL_MS_CONFIG}} is solely meant to be applied to
{{KafkaConsumer.poll()}} and it's incorrect to use it for the
{{NetworkClient}}. If the config is increased, this can lead to a infinite
rebalance and rebalance on the client side is increased and thus, the client is
not able to meet broker enforced timeouts anymore.
