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.
