Brandon Williams commented on CASSANDRA-4023:
---------------------------------------------
bq. (Maybe it's time to add random vs sequential speed ratio as a setting,
which at least is general enough to be useful in other places.)
This sounds like a good idea, we're never going to strike a balance that's
sufficient between SSD and rotational media without a knob to turn.
> Batch reading BloomFilters on startup

> The difference of startup times between a 0.8.7 cluster and 1.0.7 cluster
> with the same amount of data is 4x greater in 1.0.7.
> It seems as though 1.0.7 loads the BloomFilter through a series of reading
> longs out in a multithreaded process while 0.8.7 reads the entire object.
> Perhaps we should update the new BloomFilter to do reading in batch as well?
