What is the biggest Couchbase cluster nodes number?

Question

any body knows what is biggest couchbase cluster has been deployed, since there are lot of info broadcast from each node, i am doubt on the scalability

thanks

Answer 1

Check out this article, it covers the growth of the game 'draw something '. They went from a 6 node cluster to a 90 node cluster in 8 weeks due to rapid growth. They also had zero downtime in adding nodes to the cluster and at week 6 were processing 3000 drawings a second.

Edit

Check slide 16 on this link, cluster size of 100+ for Viber

I would like to answer this question differently than a "simple number of nodes". In your question you are talking about scalability and some "doubts" about it.... And as you can case, as Couchbase, I have no doubts about the scalability...

When people are using Couchbase, like any NoSQL solution, they have specific use case in mind for their data. And each use case have a specific data "life cycle" (volume, throughput, expiration, ...) So what do you have in mind when you are talking about scalability?

For example I have been working on a project where we have a 20 nodes cluster processing 650,000 op/s with 30% of mutation of the data. For this specific use case, no need to go bigger. You can see in other use case like Draw Something with 80/90 nodes ~50 million total users, 16 million daily users, 2 billion documents...

So instead of talking of "hypothetical" size of the cluster, I would like to understand your use case and type of deployment (available hardware/VMs) to define what will be a good topology.
