Re: [Consitency on cqlsh command prompt]
DO you have 2 data centers? QUORUM is (total_replicas/2)+1 You may want LOCAL_QUORUM On Tue, Dec 16, 2014 at 11:47 PM, nitin padalia padalia.ni...@gmail.com wrote: Hi, When I set Consistency to QUORUM in cqlsh command line.

Re: [Consitency on cqlsh command prompt]
I believe the problem here is that the consistency level it is showing you is not the number of nodes that need to respond, but the enum value that corresponds to QUORUM internally. If you would like, you can file an improvement request on the Apache Cassandra Jira.

Thanks! Philip/Ryan, Ryan I am using single Datacenter. Philip could you point some link where we could see those enums. -Nitin On Dec 17, 2014 7:14 PM, Philip Thompson philip.thomp...@datastax.com wrote: I believe the problem here is that the consistency level it is showing you is not the number of nodes that need to respond, but the enum value that corresponds to QUORUM internally.

This is something that could easily be improved in cqlsh. I'll get a ticket open today. Adam On Wed, Dec 17, 2014 at 8:38 AM, nitin padalia padalia.ni...@gmail.com wrote: Thanks! Michael.
