Flavio Pompermaier commented on PARQUET-34:
-------------------------------------------
I think that introducing contains() is definitely not as simple as mentioned at
the beginning of this post.
It would require a huge rework of parquet-column in order to handle Collections
(PARQUET-35) and filtering on row groups (see PARQUET-43).
I'll be glad to contribute but I can't do it alone without a direct support
from your side (at least to agree on the changes to apport at the core code).
Do you think you can spend some time to actively focus with me on this task in
the next days...?
