Connect Kafka to Clickhouse with No Code and No Servers

The article describes a step-by-step process for connecting a Kafka topic to a Clickhouse table using Upstash Kafka and Clickhouse Cloud without the need for hosting a server or backend service. It begins with setting up Clickhouse through Clickhouse Cloud, which offers a 30-day free trial, and creating a table using SQL. The next step involves setting up a serverless Kafka cluster through Upstash, selecting an appropriate region for optimal performance, and creating a topic for data streaming. The article then details configuring a JDBC sink connector on the Upstash console by manually entering specific configuration settings to facilitate data transfer between Kafka and Clickhouse. Finally, it guides users on testing the setup by sending JSON messages to the Kafka topic and verifying data population in the Clickhouse table, while noting that Upstash plans to introduce a managed schema registry service to streamline operations.
