 From here, we could [set specific keys](./core/logger.md#append_keys-method){target="_blank"} to add additional contextual information about a given operation, [log exceptions](./core/logger.md#logging-exceptions){target="_blank"} to easily enumerate them later, [sample debug logs](./core/logger.md#sampling-debug-logs){target="_blank"}, etc.
