Meltano

I’m surprised to see there’s no mapper plugin for snake casing _all_ properties (as most databases won’t allow arbitrary symbols).

Would this be useful to others if I were to make this publicly available (or contribute to an existing mapper repo)?

Finally got around to writing a mapper for standard out-of-the-box key and value transformations. Mostly for sanitizing fields and changing keys to suit targets (eg from camel case to snake case): <https://github.com/rubenvereecken/map-sanitize/blob/main/map_sanitize/mapper.py>

What would be the steps to get this published to the Meltano Hub?

Fork <https://github.com/meltano/hub>, add a definition in `_data/meltano/mappers` and make a PR back.
