Alex Levenson commented on PARQUET-41:
--------------------------------------

This will require some planning and discussion around parquet-format.
We need to choose how we will serialize a bloom filter into parquet statistics, 
how it's size will be configured, etc.
But ultimately it needs to be a bloom filter easily deserialized from C++, and 
it needs to be durable (so java.io.Serializable  or anything similar won't work 
here.)

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