SQLAlchemy connection disconnects after 5 minutes of inactivity with ProxySQL 2.0.9

[hert525]

Description:

I am experiencing an issue with ProxySQL version 2.0.9 where connections to MySQL through SQLAlchemy disconnect after about 5 minutes of inactivity. Both ProxySQL and MySQL have wait_timeout and interactive_timeout set to 4 hours, but connections are still being dropped much sooner than expected.

Steps to Reproduce:

Set up ProxySQL 2.0.9 and configure wait_timeout and interactive_timeout on both ProxySQL and MySQL to 4 hours.
Connect to MySQL through ProxySQL using Python with SQLAlchemy.
Allow the connection to remain idle for 5 minutes.
Observe that the connection disconnects and an error message is displayed.
Expected Behavior:

The connection should remain active for up to 4 hours of inactivity, consistent with the wait_timeout and interactive_timeout configurations.

Observed Behavior:

The connection disconnects after about 5 minutes of inactivity. The error message received is:

The client was disconnected by the server because of inactivity, see wait_timeout and interactive_timeout

Additional Information:

ProxySQL version: 2.0.9
SQLAlchemy version: [specify your SQLAlchemy version here]
Python version: [specify your Python version here]
Both wait_timeout and interactive_timeout are configured to 4 hours on both ProxySQL and MySQL.
Any insights or suggestions to resolve this issue would be greatly appreciated. Thank you!
