This feature controls how the connector handles existing connections when a manual switch is invoked.

When a graceful switch is invoked via cctrl, by default the Connector will wait for five (5) seconds to allow in-flight activities to complete before forcibly disconnecting all active connections from the application side, no matter what type of query was in use.

If connections still exist after the timeout interval, they are forced closed, and the application will get back an error.

This timeout is adjusted via the tpm option --connector-disconnect-timeout.

For example, to change the delay to 10 seconds:
