Hi, You could use node filters: https://ignite.apache.org/docs/latest/services/services#node-filter example of node filter: https://github.com/apache/ignite/blob/master/examples/src/main/java/org/apache/ignite/examples/computegrid/ComputeFibonacciContinuationExample.java
In general, it is not recommended to segregate nodes based on individual responsibility, as it negates the main advantage of automatic scaling, failover and backup. see here: https://ignite.apache.org/docs/latest/distributed-computing/distributed-computing Thanks, Alex -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
