Question

When I want to use kafka as the storage layer for eventmesh,the runtime start fail.

The configuration is as follow:

connector plugin

eventMesh.connector.plugin.type=standalone

storage plugin

eventMesh.storage.plugin.type=kafka

Does eventmesh support kafka now? If support,how to start eventmesh with kafka?

Kafka storage plugin is supported. There is a Kafka connector PR still WIP. You may look for its progress here: https://github.com/apache/eventmesh/pull/4180.

First, it will be better if you can modify this issue title to something concrete. "Question title" is a bad title.

Then, Kafka storage plugin is supported. You can provide the error stack information for community accurately locating your problem.
