Thanks Jeremy.
Any way I could detect that such a truncate operation was performed on the
table? Does it leave a trace that the truncate happened anywhere?
Best regards,

Everything in that table is deleted. There's no mutation or anything in the
commitlog. It's a deletion of all the sstables for that table. To make sure
everything is gone, it first does a flush, then a snapshot to protect against a
mistake, then the truncate itself.

Hi Folks,
I am trying to read Mutations from commit log files through an
implementation of CommitLogReadHandler interface.
For a truncate CQL operation, I do not see a Mutation object.
Does C* skip writing the truncate operation into the commit log file?
Thanks for your help.
Best regards,
Sa
Nevermind. I figured out this is happening on all nodes where the tokens got
moved. So, explains the big streaming going around in the cluster.

The node that invoked removenode is entirely irrelevant, any node can
invoke it.

But I don't understand how the replica count is getting restored here. The node
that invoked removenode only owns partial ranges.

Hello,
Recently, I started noticing an interesting pattern. When I execute
"removenode", a subset of the nodes that now own the tokens result it in a CPU
spike / disk activity, and sometimes SSTables on those nodes shoot up.
After looking through the code, it appears to me that below function f
We have lots of dedicated Cassandra clusters for large use cases, but we
have a long tail of (~100) of internal customers who want to store < 200GB
of data with < 5k qps and non-critical data. It does not make sense to
create a 3 node dedicated cluster for each of these small use cases. So we
have
