> Consider to enforce application.server <server>:<port> format at config level

> Key: KAFKA-17164
> URL: https://issues.apache.org/jira/browse/KAFKA-17164
> Project: Kafka
> Issue Type: Improvement
> Components: streams
> Reporter: Matthias J. Sax
> Assignee: sanghyeok An
> Priority: Minor
> Labels: needs-kip
>
> KafkaStreams support configuration parameter `application.server` which must
> be of format `<server>:<port>`.
> However, in `StreamsConfig` we accept any `String` w/o validation, but only
> validate the format inside `KafkaStreams` constructor.
> It might be better to add an `AbstactConfig.Validator` and move this
> validation into `StreamsConfig` directly.
> This would be a semantic change because `new StreamsConfig(...)` might now
> throw an exception. Thus we need a KIP for this change, and it's technically
> backward incompatible... (So not sure if we can do this at all – expect for a
> major release? – But 4.0 is close...)
> The ROI is unclear to be fair. Filing this ticket mainly for documentation
> and to collect feedback if people think it would be a worthwhile thing to do
> or not.
