Hello, There is no need to restart the cluster if you want to create a new cache as dynamic cache creation is supported: https://apacheignite.readme.io/docs/jcache#section-dynamic-cache
Do you use native persistence or do you run in-memory? If this doesn't work for you, could you please describe the case a bit? Best regards, Anton -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
