Can we clarify/document the behavior on the KIP?

Thanks for the questions Matthias!

1. I think we can check the config in the constructor which doesn't take
the client supplier as a parameter. This one:

     public KafkaStreams(final Topology topology,
                         final Properties props) {
     ...
     }

If users provide a client supplier in another constructor, the config won't
be checked and the provided one will be used, which is code would override
the config.

2. I'm fine with `default.client.supplier` and make it the
`DefaultKafkaClientSupplier`

Thanks,
Hao

What is the behavior if users set the config and also pass in a client
supplier into the constructor?

Following other config/API patterns we use, it seems the best thing
would be if the code would overwrite the config?

If we do this, should we change the config name to
`default.client.supplier` and not make it `null`, but set the default
supplier we use currently?

This way, the config and code would behave the same as other configs
like `default.timestamp.extractor` and similar.

Hi all,

I have submitted KIP-884 to add config to configure KafkaClientSupplier
and
would like to start a discussion:
