Stu Hood commented on CASSANDRA-633:
------------------------------------
Ah, bummer. CSLM is really hard to beat... the JVM devs did some great work
there.
I'm still experimenting with the flattened namespace idea in the unified-index
branch: it has blossomed into a redesign of the data-file format =x If the
flat namespace works well for the disk format, I think we should experiment
with doing it for Memtables as well (aka, Memtable as map of (key,name1,name2)
-> value).
