> The current BloomFilter implementation requires a BitSet of (bucket_count *
> num_keys) in size, and that calculation is currently performed in an integer,
> which causes overflow for around 140 million keys in one SSTable.
> Short term fix: perform the calculation in a long, and cap the value to the
> maximum size of a BitSet.
> Long term fix: begin partitioning BitSets, perhaps using Linear Bloom Filters.
