Subject question on capacity planning
Date Wed, 29 Jun 2011 12:36:30 GMT
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? Given this amount of data, would you recommend node storage at 2TB per node
or more? This application will have a heavy write /moderate read use profile.
