Sorry, I didn't have time lately to look into this. But I would be very interested to somehow provide distinct count estimates for parquet files, mostly for Int64 columns. If one would use distinct estimates as part of the key=value metadata, we would first need to agree on a standard representation of these estimates. Ideally this would be the same across different language implementations. That's why I thought it would be easier to use the "distinct_count" field. But I get it's not the cleanest approach. -- This is an automated message from the Apache Git Service.
