Subject 200TB in Cassandra ?
Date Thu, 19 Apr 2012 11:12:19 GMT
Hi,

One of the projects I am working on is going to need to store about 200TB
of data - generally in manageable binary chunks. However, after doing some
rough calculations based on rules of thumb I have seen for how much storage
should be on each node I'm worried.

  200TB with RF=3 is 600TB = 600,000GB
  Which is 1000 nodes at 600GB per node

I'm hoping I've missed something as 1000 nodes is not viable for us.

cheers
