Parquet with type struct

[benjdv]

As announced in documentation (https://github.com/adjust/parquet_fdw) It will be useful to supports the column type: STRUCT.
The STRUCT parquet column type may be converted into TEXT or JSON in SQL.

Hi,

that was our intention in the first place, we also had some nested structures. But unfortunately libparquet (which we use to read parquet files) does not fully support them. Particularly it doesn't support lists of structs (see this issue), but it should work fine with simpler structs without repetition. I think it makes sense to at least support those is parquet_fdw. I'll see what I can do.

Hi,
any update on this feature, please? The underlying issue has been solved.
I know, it is the feature, so I'll be happy also with the answer " we don't have a plan for this in foreseeable future" --> I would know I need to find the workaround.
Thanks a lot.

Looks like libparquet now supports STRUCT based on the latest update from the issue

Hi,
has anyone tested the support for STRUCT in parquet_fdw? Based on the latest comments, it seems that libparquet now supports STRUCT. It would be great to know if anyone has successfully used it or has any insights about its implementation.
Thanks!
