Hazelcast with Hundreds of Nodes

One of the frequent question about hazelcast:

Will it scale up to hundreds of nodes?

Answer from Talip (founder of Hazelcast) in mail group:

Forming 100+ node cluster is not hard and it will be as stable as your networking infrastructure. Running distributed executions is fine too as long as your application can handle execution failures and you don’t make a distributed call within another distributed call.

To get less affected by the split-brain issues, smaller clusters are recommended. Try to run less number of execution nodes (cluster members) and submit your executions from any number of clients. Clients can scale to thousands easily.
