LOGGING

LoggingStep is a pipeline step that simply logs the input data keys (and optionally values) and returns the input data unchanged.

Configs	Descriptions
logLevel	This is similar to how standard logging frameworks define logging categories. Default value is INFO. Another available options are TRACE, DEBUG, WARN and ERROR.
log	An enum specifying what part of a data instance should be logged. Default value is KEYS.
keyFilterRegex	A regular expression that allows filtering of keys - i.e., only those that match the regex will be logged.
