Personally I think this is good. However we have duplicate docs in the Delta Lake connector. And parquet_writer_batch_size seems to be NOT supported by that connector .. so the implementation is a mess in the sense that it is NOT the same for all connectors.

Wdyt @electrum should be done here .. maybe we get rid of the docs in the Delta Lake connector and instead add it here. And check that the connectors implement all of them?

Thoughts @findinpath @raunaqmorarka ?

@devozerov stay tuned until we discussed here

I don't think we will get to the point where all data lake connectors have exactly same parquet properties. E.g. writer validation is something that was implemented only for hive connector.
