   Just to add I think this will be simplified or solved once DB access from 
dag-processor also moved to use task-sdk. I also want to add passing 
`echo_pool=True` displays verbose logs about the lifecycle of the pool which 
might be useful here.

   I was also checking on other options
   
   1. Option 1 to use `NullPool` when mysqlclient is used but will result in 
performance impact that sqlalchemy docs describes as modest.
   2. Use pymysql which is a Pure Python implementation and might not have this 
behaviour though again not as performant mysqlclient in C.
