If you have the time, I would suggest creating a prototype with both databases
and trying it out. You should also have some idea of how this system might
evolve in the future. It is important because that could very well help you
make a decision. Mongo or Cassandra may work but if your

When you don't have any disk space anymore (or not much), there are things
you can do :
*Make some space:*
- Remove snapshots (nodetool clearsnapshot)
- Remove any heap dump that might be stored there
- Remove *old* -tmp- SSTables that could still be around.
- Truncate unused table /
Hi All,
I recently upgraded my non prod cluster from 3.10 to 3.11.2.
It was working fine for a 1.5 weeks then suddenly nodetool info startee
reporting 80% and more memory consumption.
Intially it was 16gb configured, then i bumped to 20gb and rebooted all 4
nodes of cluster-single DC.
Now after 8
