Optimize config for large datasets

**Feature request**
It would be great to have timeout for handlers.

**Use case**
Many users need this functionality for production deployments.

**Implementation idea**
Add a new config option `enable_timeout` with default `false`.

Start by locating the handler implementation and configuration loading code in the Operator repository; the issue does not name specific files or tests. Trace how handler execution currently works, then determine the expected timeout behavior and verify that the new enable_timeout option defaults to false and is covered by tests.
