You could see an example of using ColCursor in the RecordCursor implementation. It may not make sense to use it on nested schemas, but may be useful with flat schemas.

kinda tough to get. anyway i will close it.

Doesn't seem to be user-facing type of functions.

One thing I can't answer with Parquet.jl is that how do I read a full column? It's very hard to figure it out despite parquet being a columnar-format. The examples in the readme seems to be for reading it row-by-row.
