Subject Re: Kafka streams consumer/producer throttling
Date Wed, 28 Nov 2018 18:08:54 GMT
Hi Andrey,

You're right that Streams does not allow users to directly set client ids
for the embedded producer / consumer in order to maintain uniqueness. If
you take a look at `StreamsConfig#getProducerConfigs` for example you'll
see at the end we always override the client id configs.

Right now you'll have to use the constructed client ids to set the configs,
as well as acls. We have a JIRA open for adding a Streams role in those
tools for easy operations but atm manual settings are unfortunately not
avoidable.

As for wildcards, for acls there are support for prefix wildcard but I
think we do not have similar support for general config settings for entity
names yet.
