Hi Christos, Thanks for getting back to me.
There is no specific need for it - I am just trying to get my head around for the best practices in that case data nodes does make sense to me to perform the computation. To be honest just a bit confused with the Cluster groups and trying to find a use case for it (apart from collecting metrics and broadcasting). Cluster API does make sense and already using it but then stuck with groups where it can be useful or maybe I am thinking too much :) Thanks, Luqman -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
