:: DeveloperApi ::
Utility trait for classes that want to log data. Creates a SLF4J logger for the class and allows
logging messages at different levels using methods that only evaluate parameters lazily if the
log level is enabled.
NOTE: DO NOT USE this class outside of Spark. It is intended as an internal utility.
This will likely be changed or removed in future releases.
