So the bloom filters reside in
We do have a lot of small values, hundreds of millions
of columns in a columnfamily.
I count the total size of *-Filter.db files in my
keyspace, it's 436,747,815bytes.
I guess this means it won't consume a
major part of 10g heap space

Are the 300 GB made up of *really* small values? Per SS table bloom
filters do consume memory, but you'd have to have a *lot* of *really*
small values for a 300 GB database to cause bloom filters to be a
significant part of a 10 GB h eap.
