* Define all structured logging keys in `LogKey.scala`, and sort them alphabetically for ease of search.
* Use `UPPER_SNAKE_CASE` for key names.
* Key names should be both simple and broad, yet include specific identifiers like `STAGE_ID`, `TASK_ID`, and `JOB_ID` when needed for clarity. For instance, use `MAX_ATTEMPTS` as a general key instead of creating separate keys for each scenario such as `EXECUTOR_STATE_SYNC_MAX_ATTEMPTS` and `MAX_TASK_FAILURES`. This balances simplicity with the detail needed for effective logging.
* Avoid abbreviations in names. Use `APPLICATION_ID` instead of `APP_ID`.
* Use abbreviations in names if they are widely understood, such as `APP_ID` for APPLICATION_ID, and `K8S` for KUBERNETES.
