when pid column of sys.session will be null in mysql?
Am using mysql 5.7.19-log server, I am working on application monitor tool where i need to monitor session details of a mysql server. In the process came to know that pid column can be null in sys.session table. i want to know what are the cases in which pid can be null?
My intention of the question is for real-time scenarios, not like insert null for column pid (or) update pid as null etc. I want to know the use case's when pid will be null.
For example:
If you connect to Postgres DB server with socket connection then pid column will be null, I want, like this use cases.
