I use Pelops and have been very happy. In my opinion the interface is cleaner
than that with Hector. I personally do like the serializer business.

I have an index to a column IX in column family A.
How would I go about compacting that? I have tried nodetool compact keyspace

But that complains "Unknown table/cf pair"
I'm sure there must be some simple magic to make this happen. I just cannot
tell what it is.
JNA setup correctly? (You should see a couple of log
messages about it shortly after startup.) Truncate also performs a snapshot by
default.

nodes enter a nasty spiral of constant flushing, constant compactions, high
heap usage, instability and high latency.

I have repeated the test on two quite large machines 12 core, 64 GB as5 boxes
and still observed the problem. Interestingly about at the same point.
Anything I can monitor... perhaps I'll hook the Yourkit profiler up to it to
see if there is some kind of leak?

If the node with token 0 dies and we just want it gone from the cluster we
would do a nodetool move 0. Then we monitor using nodetool ring it seems to be
stuck on Moving forever.
Any ideas?
How does counters affect this? Why would be different?
