Pausing Connector Task in between polling interval

[kinihun]

Hi,
I have a JDBC Source Connector pulling data from a database on a daily schedule.
I need to prevent the associated task restarting if the underlying Kubernetes Cluster nodes are rebooted or redeployed.

I use Kured to reboot my nodes when there is an OS patch that requires reboot. This is an automated process but it has the unintended consequence of restarting my Connectors when they are moved between Nodes and hence Kafka Connect Workers.

Sorry, I'm not really sure what exactly are you talking about. Maybe you can decribe it step by step or something to make it easier to understand?

When a node is rebooted and the associated task is reassigned to another worker, the task is restarted. In the case of a JDBC source connector doing bulk pull from a database at a periodic interval, this will trigger another pull.
I’m trying to prevent this

Sorry, I still not follow. This is how COnnect is designed to work. The tasks are scheduled to the workers to amke sure they can run. This is the first time someone is complaining that his connector runs. Normally this is desired and I do not understand why would you not want it.

Ideally, I’d prefer that the task be in paused state in between polling interval. I understand that my question may seem counter to the intended operation of connect workers but I have a real usecase.
Perhaps someone else understands my request, just looking for suggestions

Still don't follow it. The polling is done by Kafka and is happening possibly very often. So what does pausing between polling interval mean? You can pause a connector. But if it is running, it will be polled regularly regardless what you do with the worker.
