# Compatible messaging systems

The following tables provide information on the supported versions of Kafka, which is the recommended messaging system to use with Talend server modules.

In the following documentation:

* Recommended: designates an environment recommended by Qlik based on experience and customer usage.
* Supported: designates a supported environment for use with the listed component or service.
* Supported with limitations: designates an environment that is supported by Qlik but with certain conditions explained in notes.

Information noteWarning: When Apache Kafka is installed on a Windows machine, the Kafka broker cannot delete old log files. This is due to how it manages files on Windows operating systems. If you install Apache Kafka on Windows, it will eventually stop working because it cannot purge old log files, which can cause Talend Data Preparation, Talend Data Stewardship, and Talend Dictionary Service to stop working. Talend recommends installing Apache Kafka on a Linux machine.
