Re: cql3 - adding two numbers in insert statement

Hi Shreyas, It's good to paste the error if you want us to give you a quick and good answer. In this case the table schema would have been helpful as well. That being said, you are probably missing some quotes around the values for 'key' and 'column1'. C*heers, --- Alain

Very slow cluster

Hi to all: I am having some problems with two client's cassandra:3.0.8 clusters i want to share with you. These clusters are for QA and DEV. The cluster 1 (1 DC) is composed by 3 vm (heap=4G, RAM=8G) sharing the same physical machine and sharing one ssd. I know this is not the best environment

Re: Running Cassandra in Integration Tests

Sorry for bumping this old thread, but what would be your suggestion for programmatically start/stop nodes in a cluster? I'd like to make some experiments and perform QUORUM writes against a cluster (REPLICATION=3) with alternatively 2 or 3 nodes up, starting/stopping/restarting nodes in the

RE: [Cassandra] nodetool compactionstats not showing pending task.

Hi , I will try with JMX but I try with tpstats. In tpstats its showing pending compaction as 0 but in nodetool compactionstats its showing 3. So, for me its seems strange. Thanks & Regards, Abhishek Kumar Maheshwari +91- 805591 (Mobile) Times Internet Ltd. | A Times of India Group Company

Restrict cassandra to number of cpus

Hi All - Is it possible to restrict cassandra with some limited number of cpus/cores on a given bix? There is one JVM parameter to do that but all thread pools dont respect that setting. -D cassandra.available_processors Is there any other way to achieve this ?
