I'm going through the process of specing out the hardware for a Cassandra cluster. The relevant specs:
- Support 460 operations/sec (50/50 read/write workload). Row size ranges from 4 to 8K. - Support 29 million objects for the first year - Support 365 GB storage for the first year, based on Cassandra tests (data + index + overhead * replication factor of 3) I'm looking for advice on the node size for this cluster, recommended RAM per node, and whether RF=3 seems to be a good choice for general availability and resistance to failure. I've looked at the YCSB benchmark paper and through the archives of this email list looking for pointers. I haven't found any general guidelines on recommended cluster size to support X operations/sec with Y data size at RF factor of Z, that I could extrapolate from. Any and all recommendations appreciated. Thanks, Brian
