-----------------------------
Attachment: 0001-CASSANDRA-3762-v5.patch
>>> It means that the method don't return what what it should and should be
>>> renamed to *estimate*SerializedSize but as we would to the same for all of
>>> the rows in the cache I don't see how it would harm LRU if we do the real
>>> calculation.
If you are getting hot n keys, it will be making hot keys even more hotter....
renamed.
>>> It does not
the idea is that the newer cache will delete the older one :) so it is a no op
after that.... anyways fixed it just for the sake of it :)
>>> What about this one?
As we are using estimate not the real value we need to use the
serializedSize.... Thats how it was earlier too :)
> AutoSaving KeyCache and System load time improvements.

> CASSANDRA-2392 saves the index summary to the disk... but when we have saved
> cache we will still scan through the index to get the data out.
> We might be able to separate this from SSTR.load and let it load the index
> summary, once all the SST's are loaded we might be able to check the
> bloomfilter and do a random IO on fewer Index's to populate the KeyCache.
