Hi, Make sure that your keys are go to specific partition. Only one node could keep that partition at a time (except backups, of course). To do that, you may use @AffinityKeyMapped annotation [1].
Additionally you can implement your own AffinityFunction that will assign partitions that you need to specific node(s). You may try to extend RendezvousAffinityFunction for that. In this case you may assign number of partitions to proper node that you need.
