Tom Bentley commented on KAFKA-9635:
------------------------------------
[~kkonstantine], [~cmccabe] can you offer any insights into the future use of
these methods?
> Should ConfigProvider.subscribe be deprecated?
> ----------------------------------------------
>
> Key: KAFKA-9635
> URL: https://issues.apache.org/jira/browse/KAFKA-9635
> Project: Kafka
> Issue Type: Bug
> Reporter: Tom Bentley
> Assignee: Tom Bentley
> Priority: Minor
>
> KIP 297 added the ConfigProvider interface for use with Kafka Connect.
> Its seems that at that time it was anticipated that config providers should
> have a change notification mechanism to facilitate dynamic reconfiguration.
> This was realised by having {{subscribe()}}, {{unsubscribe()}} and
> {{unsubscribeAll()}} methods in the ConfigProvider interface.
> KIP-421 subsequently added the ability to use config providers with other
> configs (e.g. client, broker and Kafka Streams). KIP-421 didn't end up using
> the change notification feature, since it was incompatible with being able to
> update broker configs atomically.
> As things currently stand the {{subscribe()}}, {{unsubscribe()}} and
> {{unsubscribeAll()}} methods remain in the ConfigProvider interface but are
> not used anywhere in the Kafka code base. Is there an intention to make use
> of these methods, or should they be deprecated?
