Description: is_connected() is checked every time a statement is executed. This is not really necessary and reduces the overall performance. How to repeat: Check the code: def exec_mysql_stmt(cnx, stmt_str, options=None): ... if cnx is None or not cnx.is_connected(): raise _errors.DatabaseError("Invalid database connection.") Suggested fix: Improve the code and check whether a connection is fine or not only right after retrieving it from the pool.
