Are you sure there is no TTL set on your data? It might explain the shrink
in sstable size after compaction.

Hi Phil,
I found an interesting blog entry that may address your problem.

It seems that compaction is skipped for stables which so mit satisfy a certain
read rate. Please check.
Kind regards

Netflix probably does, managed with Priam.

As far as I know nodes are identified by ip address and ports defined in
yaml. If you carefully prepare configuraton you should be able to run
multiple Cassandra processes on single box participating in different
clusters. If you decide to use separate ip address and default ports it
should be
Probably! I'll give that a try, thanks!

Thanks Rob, I didn't realize that you could use the initial_token when using
vnodes.
I see what you mean now that with RF=N having multiple vnodes is not
actually achieving anything unless we add further nodes, we hadn't really
considered that when we initially installed with the default yaml
Hi Andreas,
So does that mean it can compact the 'hottest' partitions into a new sstable
but the old sstables may not immediately be removed so the same data could
be in more that one sstable? That would certainly explain the difference we
see when we manually run nodetool compact.
Thanks

What I noticed is after sometime irrespective I run cassandra from other
