d side by side is
also an example of such modularity and optionality.*
(For completeness, I note that explicitly adding pluggability as a
requirement means that it is no longer necessary to also add a LOCAL_SERIAL
option to Accord itself, although that is of course still an option.)

Catching OOME is a bug, not a fix. OOME is the JVM saying "I give up;
you're screwed." The JVM isn't stable anymore.

The workarounds we can apply at the Cassandra level have too high a

It sounds like an interesting project but I don't think it would be a
good fit for GSoc because it's just too different to be a good

Because traditional B-trees are update-in-place, and although CouchDB
has an append-only B-tree, it's limited to one writer at a time which
is (one reason)
Table is the old name for Keyspace. I agree that CFs are closer to
the traditional use of the "table" concept (which is why we changed
it).

Definitely let us know if you find that changing the GC options helps.
We have tried to get some of the low-hanging fruit there but nobody
has put serious effort into tuning it.

Also: there is nothing stopping your app from pooling connections on a

partition on keyspace per customer, then that is what I would do.
