Hi all

I have been given a 15 nodes C* 2.2.8 cluster to manage which has a large size 
KS (~800GB). Given the size of the KS most of the management tasks like repair 
take a long time to complete and disk space management is becoming tricky from 
the systems perspective.

This KS size is going to go up in future and we have a business requirement of 
long data retention here. I wanted to share this with all of you and ask what 
are my options here, what would be the best way to deal with a large size KS 
like this one. To make situation even trickier low IO latency is expected from 
this cluster as well.

Thankful for any suggestions/advice in advance.
