  -H 'Content-Type: application/json' \
  -d '{"sql": "create stream demo() WITH (FORMAT=\"JSON\", TYPE=\"edgex\")"}'

2、create rule

  }

Question：
When creating a stream,TYPE="edgex"，What is the meaning of “TYPE” ，and “ cannot get the plugin file path: invalid name edgex: not exist”，the “edgex” is the file “edgex.yaml” in etc/source?? this file is exists.

Could you please refer to this link - #569? It can be solved by compile a native build with edgex support.

[zhu-zyq]

I was build kuiper with "make build_with_edgex",so Kuiper should support EdgeX. Kuiper's plugins/source folder is empty.

[jinfahua]

The edgex will be compiled into kuiperd binary file, it will not be a separated so file in plugins/source folder. From your log, it shows that the edgex has not been compiled into kuiperd binary file.

[zhu-zyq]

Shouldn't Kuiper be compiled into edgex enabled binaries?
How can I check whether edgex is compiled into kuiperd binary?

build kuiper with "make build_with_edgex" ,return "Build successfully"
_build/log/ stream.log file shows "Listen error: listen tcp :20498: bind: address already in use" file="server.go:72"
Thank you very much.

The separated binary version of Kuiper does not include EdgeX source because EdgeX requires additional libraries (zeromq library), and Kuiper cannot be started without installing the lib. Kuiper is not only for EdgeX, so it will confuse user that do not use EdgeX.

build kuiper with "make build_with_edgex" ,return "Build successfully"
_build/log/ stream.log file shows "Listen error: listen tcp :20498: bind: address already in use" file="server.go:72"
Thank you very much.

It seems there already have an existed kuiperd process, you need to kill it.

[zhu-zyq]

Thank you very much for your patient answers . I understand what you mean. But I think it’s not a compilation problem . Because I ran the source code of edgex-go, installed zeromq, and compiled and ran successfully. The readme file under kuiper is written to be compiled with "make build_with_edgex", which means that this version of kuiper contains the source of Edgex.
When I get data from the EdgeX Message bus(MQTT server) when creating a stream, the rule state is running.
