Optimize config for large datasets

**Feature request**
It would be great to have logging for components.

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

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

No files or tests are named. Start by locating the configuration entry point and the code that handles component logging; add the `enable_logging` option with a default of `false`, then verify that enabling it produces component logs and that the default remains disabled.
