Alex Levenson commented on PARQUET-41:
--------------------------------------
To clarify, I'm not saying the C++ has to use the bloom filter at runtime right
away, but we should not use a binary format that would make it impossible /
difficult for the C++ impl to use it if it wanted to. And I think it would also
be bad news if each impl serialized bloom filters in their own way.

> For row groups with no dictionary, we could still produce a bloom filter.
> This could be very useful in filtering entire row groups.
