Swapping can come handy if a cluster node reaches its maximum memory capacity and, instead of failing with an out-of-memory exception, you can keep it alive by swapping out data before the cluster is scaled out. Once you add a new cluster node, the data will be rebalanced and the first node will free its memory space up.
More on swapping here: https://apacheignite.readme.io/docs/swap-space If you need persistence regardless then consider Ignite native persistence as advised by others. - Denis On Thu, Jan 30, 2020 at 10:07 PM ashishb888 <[email protected]> wrote: > Thank you Evgenii! > > I can understand that enabling swap may decrease the performance. > Keeping in that mind I wanted to see what actually happens after enabling > swap. > For that I need to know how to enable swap on a specific node without > affecting other nodes in the cluster. > > BR, > Ashish > > > > -- > Sent from: http://apache-ignite-users.70518.x6.nabble.com/ >
