Our colleague Mikhail Filimonov just published an excellent ClickHouse Kafka Engine FAQ. It provides users with answers to common questions about using stable versions, configuration parameters, standard SQL definitions, and many other topics. Even experienced users are likely to learn something new.
But what if you are getting started and need help setting up Kafka and ClickHouse for the first time? Good news! This article is for you.
Kafka is a popular way to stream data into ClickHouse. ClickHouse has a built-in connector for this purpose -- the Kafka engine. Our friends from Cloudfare originally contributed this engine to ClickHouse. The Kafka engine has been reworked quite a lot since then and is now maintained by Altinity developers. It is not always evident how to use it in the most efficient way, though. We tried to fill the gap with a Kafka webinar, which was a success. In this article we collected typical questions that we get in our support cases regarding the Kafka engine usage. We hope that our recommendations will help to avoid common problems.Read More
