Alex Levenson commented on PARQUET-41:
--------------------------------------
Right, so while this works for temporary storage / transport of java objects,
it's not a durable format with guaranteed stability over time. If the algebird
bloom filter changes later, it will serialize differently, etc. So I think we
need to still define a thrift / binary format for storing the bloom filter.

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