So, in our experience, the amount of storage overhead is much higher. If you
plan on storing 120TB of data, you will want to expect storing 250 TB of
data on disk after the data over head. And then since you have to leave 50%
of storage space free for compaction, you're looking at needing about
if I'm planning to store 20TB of new data per week, and expire all data every 2
weeks, with a replication factor of 3, do I only need approximately 120 TB of
disk? I'm going to use ttl in my column values to automatically expire data. Or
would I need more capacity to handle sstable merges?
