What is MemtableFlushAfterMinutes set to?

That sounds odd:
- do you have an idea of how many inserts per second / minute you think you are
sending?
- Is is just one node thats flushing mem tables fast?
- Can you send the column family for the super busy CF (nodetool cfstats)
- Can you send the storage-conf.xml
- Can you send the nodetool
It's compacting at a ridiculously fast rate. The pending compactions have
been growing for a while.
It's also flushing memtables really quickly for a particular CF. Like,
really quickly. Like, one every minute. I increased the thresholds by 10x
and it's still going fast.

Turns out that this is due to a larger proportion of the wide rows in the
system being located on that node. I moved its token over a little to
compensate for it, but it doesn't seem to have helped at this point.
What's confusing about this is that RF=3 and no other node's load is growing
as quick

What Replica Placement Strategy are you using (R
This node's load is now growing at a ridiculous rate. It is at 105GB, with
the next most loaded node at 70.63GB.
Given that RF=3, I would assume that the replicas' nodes would grow
relatively quickly too?

According to http://wiki.apache.org/cassandra/Operations nodetool repair is
used to perform a major compaction and compare data between the nodes,
repairing any conflicts. Not sure that would improve the load balance, though
it may reduce some wasted space on the nodes.
nodetool loadbalance wil
I know, but that's not a big enough difference to warrant the huge amount of
difference in load.

I ran cleanup on all of them and the distribution looked roughly even after
that, but a couple of days later, it's looking pretty uneven.

Hi,
Have you tried nodetool repair (or cleanup) on your nodes ?

I just increased my cluster from 2 to 4 nodes, and RF=2 to RF=3, using RP.
The tokens seem pretty even on the ring, but two of the nodes are far more
heavily loaded than the others. I understand that there are a variety of
possible reasons for this, but I'm wondering whether anybody has suggestion
