Description

From the user-zh email:

http://apache-flink.147419.n8.nabble.com/FlinkSQL-Prometheus-td8858.html

The sql operator name is too large, this resulted in a lot of memory in querying Prometheus which is not friendly in the production environment.

 

I think we can add a  switch to control the operator name in SQL.

A full name helps debug Jobs, and a short name helps to send this as metrics  which will save bandwidth, CPU consumption during compression, and downstream storage.
