Measure Latency

2011-05-24 Thread Stephan Pfammatter
What’s the recommended way of measuring latency between nodes in a cluster? By that I’m not referring to read/write latency for a given KS/CF. Basically I want to inject a row in a node A and want to see how long it takes to get to node B (assuming proper RF is set). I have already some network

Snapshot Location

I'm having difficulties setting up a 3 way cassandra cluster. Any comments/help would be appreciated. My goal is that all data should be fully replicated amongst the 3 nodes. I want to simulate the failure of one node and proof that the test column family still can be accessed. In a nutshell I

Hi, I read your post and noticed you are running Cassandra on win 2008. Do you run it in a production environment? I'm contacting you because there aren't that many windows installations. I need to provide a live Cassandra environment on win 2008 and was stumbling into some problems with node to

I don't understand all the problems yet you guys are facing. Just wanted to let you know that I'm getting my feet wet with Cassandra. In a few days/weeks I'll be re-reading all your notes again :) I'm bound to provide a production Cassandra environment based on win 2008 (I know, I know...It's b
