You can't, you typically need to add a whole new datacenter, replicate your data and traffic there, and decommission the old one -- Jeff Jirsa > On Aug 22, 2017, at 8:56 AM, techpyaasa . wrote: > > How can I decrease tokens for existing nodes? > Doesn't it create

How can I decrease tokens for existing nodes? Doesn't it create problem? On Aug 22, 2017 7:22 PM, "Vladimir Yudovin" wrote: Probably decreasing tokens number can help to mange big cluster? Best regards, Vladimir

Re: Limit on having number of nodes in C* cluster

We've been doing successful testing with multi-DC setups and 500 nodes per DC. However, I agree with Jon here. Certain things are easier/faster with e.g. 5x100 node clusters than 1x500 node cluster. Cheers On Mon, Aug 21, 2017 at 10:16 AM, Jon Haddad wrote: > As far

As far as I know, those 75K nodes are not in a single cluster. If memory serves correctly (and this article seems to indicate that it does http://www.techrepublic.com/article/apples-secret-nosql-sauce-includes-a-hefty-dose-of-cassandra/

Actually there are clusters of thousandths nodes: Some of the largest production deployments include Apple's, with over 75,000 nodes storing over 10 PB of data Best regards, Vladimir Yudovin, Winguzone - Cloud Cassandra Hosting On Mon, 21 Aug 2017 08:35:37 -0400 techpyaasa .

Limit on having number of nodes in C* cluster

Hi Is there any limit on having number of nodes in c* cluster. Right now we have c*-2.1.17 cluster with 3 DCs each DC with 3 groups & each group has 21 nodes. We wanted to increase the cluster capacity by adding 6 nodes per group as many of nodes disk usage crossed 65%. So just wanted to
