Re: automated CREATE TABLE just nuked my cluster after a 2.0 -> 2.1 upgrade....

Once the CREATE TABLE returns in cqlsh (or programatically) is it safe to assume it's on all nodes at that point? If not I'll have to put in even more logic to handle this case.. On Fri, Jan 22, 2016 at 9:22 PM, Jack Krupansky wrote: > I recall that there was some discussion last year about thi

Re: Need Feedback about cassandra-stress tests

Might I suggest you START by using the default schema provided by cassandra-stress. Using someone else's schema is great AFTER you use have used a standard and generally well understood baseline. >From that you can decide whether a 4 node x 2 cluster is right for you. FYI, given your 6 way replica

Re: Getting error while issuing Cassandra stress

Hi Alan, You have hit bulls eye! I used a custom yaml file for configuring keyspace, used NTT and multiple replications for each cluster, defined table schema and query and it seemed to work great!! I have some apprehensions here though. The tests that I have done did not yield results that I exp
