Subject Re: How to read Parquet “group”/list field in cpp?
Date Mon, 01 Jun 2020 03:31:56 GMT
Hi Alex,
I believe the StreamReader only supports "primitive" optional and required
column types.

There is a SkipColumns method on the StreamReader that I think should work
for skipping over the column (based on the SO question this seems to be a
possibility).  Have you tried that?

Thanks,
Micah
