> Add bloomfiltering to hfile. Should it be optional or on always? Currently,
> we bloom filter rows only, not the column + ts component, which seems good
> place to start but we size the bloomfilter with the number of entries we are
> about to flush which seems like usually we'd be making a filter too big. How
> to figure how many rows in the flush? We should use the DynamicBloomFilter
> as Andrezj does up in hadoop BloomFilterMapFile. Start small and let it
> resize as entries are added.
