----------------------------------
Summary: 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
If bootstrap brokers does contain an unhealthy server, it can break the start
of a whole Beam job. In such case, `KafkaUnboundedReader` is waiting for
`setupInitialOffset()`. In case `request. timeout.ms` is not specified it waits
some default amount or double of the timeout value. 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.
