Lokesh, The modeling will change a bit depending on your queries, the rate of update and your tooling (Spring-data-cassandra makes a mess of updating collections for example). I suggest asking the Cassandra users mailing list for help since this list is for development OF Cassandra. > On Mar

Corry, This is the Cassandra developer mailing list aimed at contributors to the Cassandra code base (not all of whom work for DataStax for example). Can I suggest you contact DataStax and ask the same question? Regards, Ryan Svihla > On Feb 3, 2016, at 9:27 AM, Corry Opdenakker

Totally depends on the load balancing policy of your driver, your data model, consistently level and you’re replication factor. The default token aware policy for the DataStax java driver up to 2.1.4 and 2.0.9 would largely behave this way if you combined it with a hot partition, and all other

Re: Performance Difference between Batch Insert and Bulk Load

Every time I've had a customer tell me batch is faster than async, it's been a code problem such as not storing futures for later, or in Python not using libev, in all cases I've gotten at least 2x speed up and often way more. - Dong On Dec 1, 2014, at 9:57 AM, Ryan Svihla rsvi...@datastax.com

Re: CQL unit tests vs dtests

2014-05-21 Thread Ryan Svihla
The standard reasoning for unit tests is specificity of errors. Well written tests suites tell you where you screwed up exactly just by the success and failure pattern, often cutting down the need for a debugger. System tests standard rational is validating these units are wired up correctly.
