Jonathan Ellis commented on CASSANDRA-3143:
-------------------------------------------
bq. I'm talking of making the key cache save being 2 files (keySave and
keySaveMetadata)
So basically "compressing" the sstable filenames into an id?
I'm actually okay with just brute-forcing it Pavel's way for now. We can
always optimize later if it's a problem. (Could we just use a compressed
writer for 80% of the benefit?)

> Caches are difficult to configure well as ColumnFamilies are added, similar
> to how memtables were difficult pre-CASSANDRA-2006.
