Jozef Vilcek commented on BEAM-9420: ------------------------------------ [~aromanenko], I apologies for late reply. `request.timeout.ms` will make Kafka's network client just wait longer for the reply from broker. The it abandons the request and try again with different broker. Kafka does not have something like `connect.timeout.ms`. It uses a request timeout for many network IO. A higher level timeout which covers `retryCount * request.timeout.ms` is needed. That is introduced in later versions by `default.api.timeout.ms`. In case of producer, this is already possible to do by setting `max.block.ms` larger than `request.timeout.ms`. For consumer, I am not aware of such option. > Configurable timeout for Kafka setupInitialOffset() > --------------------------------------------------- > > Key: BEAM-9420 > URL: https://issues.apache.org/jira/browse/BEAM-9420 > Project: Beam > Issue Type: Bug > Components: io-java-kafka > Affects Versions: 2.19.0 > Reporter: Jozef Vilcek > Assignee: Jozef Vilcek > Priority: Major > > If bootstrap brokers does contain an unhealthy server, it can break the start > of a whole Beam job. During the start, `KafkaUnboundedReader` is waiting for > `setupInitialOffset()`. Wait timeout is either a double time of `request. > timeout.ms` or some default constant. In both cases, it might not be enough > time for kafka-client to initiate fallback and retry metadata discovery via > another broker from given bootstrap list. > The client should be able to specify timeout for `setupInitialOffset()` > explicitly as a setting to KafkaIO read. -- This message was sent by Atlassian Jira (v8.3.4#803005)
