No argument there. Thanks for explaining what you were doing to encrypt client traffic! On Mon, Jan 23, 2012 at 10:11 PM, Chris Marino wrote: > Hi Jonathan, yes, when I say 'node encryption' I mean inter-Cassandra node > encryption. When I say 'client encryption' I mean encrypted traffic from th

Hi Jonathan, yes, when I say 'node encryption' I mean inter-Cassandra node encryption. When I say 'client encryption' I mean encrypted traffic from the Cassandra nodes to the clients. For these benchmarks we used the stress test client load generator. We ran test with no encryption, then with 'nod

Can you elaborate on to what exactly you were testing on the Cassandra side? It sounds like what this post refers to as "node" encryption corresponds to enabling "internode_encryption: all", but I couldn't guess what your client encryption is since Cassandra doesn't support that out of the box yet

We did some benchmarking as well. http://blog.vcider.com/2011/09/virtual-networks-can-run-cassandra-up-to-60-faster/ Although we were primarily interested in the networking issues CM On Fri, Dec 30, 2011 at 12:08 PM, Jeremy Hanna wrote: > This might be helpful: > http://techblog.netflix.c

Cassandra performance question

2011-12-30 Thread Dom Wong
Hi, could anyone tell me whether this is possible with Cassandra using an appropriately sized EC2 cluster. 100,000 clients writing 50k each to their own specific row at 5 second intervals?
