Daniel Weeks commented on PARQUET-41:
-------------------------------------

While it would be great to have them be compatible between java/C++/etc, that 
shouldn't necessarily be a requirement.  A bloom filter is an optimization, so 
if the reader doesn't know how to interpret it, it can simply be ignored.

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