Bootstrapping Question for Cassandra 2.0

Hi, could anyone please tell me whether is it possible to remove an existing node from cluster while another node is joining the same cluster? Thanks, Mir

Proper use of COUNT

Based on a recent inquiry and a recent thread of my own, and the coming support for wide rows, I'll focus in on this question that I feel needs better documentation of recommended best practice: When can the COUNT(*) aggregate row-counting function be used? Accept for relatively small or narrow

Re: Unable to perform COUNT(*) on CASSANDRA table

Hi Lokesh, Jack Krupansky sent an email to this list just this morning with all the detail you should need to understand why this happens. Steve On Mon, Apr 18, 2016 at 4:38 PM, Lokesh Ceeba - Vendor < lokesh.ce...@walmart.com> wrote: > Hello Team > >The Kafka-Storm

Multiple clustering column and ordering issue.

Hello, We have just started exploring cassandra for our project and learning basics for designing tables to meet our queries. We will have a table with following fields : user_id list_id fname lname email AND so on. We have each user with multiple lists (csv data) so have created table as below

Re: Experience with Kubernetes

We're working on that very documentation, but there's nothing about the product that is inherently single datacenter. That is to say, if you ALREADY wire together multiple data centers (via VPN, etc), then there's zero about Kubernetes that wouldn't work great today (as folks are already doing).

Looks like some problem with our monitoring framework. Thanks for you help ! On Mon, Apr 18, 2016 at 2:46 PM, Anishek Agarwal wrote: > OS used : Cent OS 6 on all nodes except *10*.125.138.59 ( which runs Cent > OS 7) > All of them are running Cassandra 2.0.17 > > output of

Re: Most stable version?

Sorry to resurrect this now, but I don't consider anything after 3.0.x stable. I wrote a blog post about this to be clear: https://www.pythian.com/blog/cassandra-version-production/ Use it and pick a version based on your needs. Regards, Carlos Juzarte Rolo Cassandra Consultant / Datastax

Alternative approach to setting up new DC

Hi, I am provisioning a new datacenter for an existing cluster. A rather shaky VPN connection is hindering me from making a "nodetool rebuild" bootstrap on the new DC. Interestingly, I have a full fresh database snapshot/backup at the same location as the new DC (transferred outside of the VPN).

Re: Traffic inconsistent across nodes

OS used : Cent OS 6 on all nodes except *10*.125.138.59 ( which runs Cent OS 7) All of them are running Cassandra 2.0.17 output of the test : host ip: 10.124.114.113 host DC : WDC distance of host: LOCAL host is up: true cassandra version : 2.0.17 host ip: 10.124.114.108 host DC : WDC
