IIRC cs stores ~3x1mb entries for each 1mb of object that you store at
default n_val. so, 300k * 3 * 9 = 810k, * 150b (to be conservative) = 1.1
GB. There will be some other static and per-entry overheads, but you
should be able to do better than that before you OOM, even on a 1 node
system.

Thank you all for you kind and quick answers
However , even on a 3 node or 5 node cluster
We're still seeing memory bloat ( only much notably slower , as load is
distributed between more machines )
it's important to stress , this is an "read-append" only cluster - This
means the data never expire
Your max file size is (far!) less than your small file size threshold - which
means that at each merge, *all* of the files will participate in the merge. No
wonder you need a lot of simultaneously open files... and long merge times too,
of course.
Try changing these parameters.

Just stop there. You got all your replicas (and fd's) on one machine. Get at
least 3 nodes in your cluster.
