Hi, Do you set backups in your cache configuration? By default in case if you have 2 data nodes without backups then you can face data loss when some of your nodes will go down. In this case, you may see not all data.
But when this node will start (with persistence) and join to topology then data from it will be available again (after rebalance). Also, you could read about: https://apacheignite.readme.io/docs/partition-loss-policies BR, Andrei -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
