Good points! This is probably it. If my understanding of those timeout config 
settings are correct (i.e. max 2 second write wait), then cassandra would be 
much more sensitive to times of VPS disk or CPU contention on a virtual 
machine. That is to say, MySQL doesn’t error out if your VPS freezes with 
CPU/Disk/Network contention for 2 seconds, but it seems that cassandra would. 
Is my understanding correct?

Best regards,
Jacob
