Hi, team:

I have a question, can I use druid-kafka-indexing-service in product? Is it production ready?

There are plenty of people using it in production. It's still a relatively young feature but it is growing up quickly. I would say go for it.

Hi Sai,

I don't think Tranquility was updated to support basic auth, so you'll have to disable auth for now if you wish to use Tranquility.

Thanks,

Jon
