[GitHub] [incubator-eventmesh] jinrongluo opened a new issue #321: Question about EventMesh Topic format

URL: https://github.com/apache/incubator-eventmesh/issues/321


   Hi Dear,
   
   I play around with EventMesh project and also studying the EventMesh codes. I see the RMQ Topic created through EventMesh, the topic name needs to be certain format. For example, "FT0-e-80010000-01-1"
   
   From the code, this method check weather the topic is valid:
   https://github.com/apache/incubator-eventmesh/blob/develop/eventmesh-runtime/src/main/java/org/apache/eventmesh/runtime/util/EventMeshUtil.java#L118
   
   I am wondering why do we have this restriction for topic names.
   
   If we want to create topic names with my own, such as "my-event-topic", what is the solution. 
   
   Thanks.

   Hi, format validation for event topics may be a bit of a problem for you at the moment. For now, you can create topics in the format FT0-E-80010000-01. Similarly, you can create topics such as:FT0-E-80010001-01, it should be noted that **e in the event topic** and **the fourth position of 80010001 is 1**  . We will remove the verification of this part later and provide relevant guidance. Thank you
