Hi Satyajit, > ensure backup partitions of a particular node is created in another node and not in same node No need to do anything, this is the default behavior: backup partitions always reside on a different node. To put it another way: every partition has a primary node and one or more backup nodes. All those nodes are different (given enough nodes in the cluster).
- AffinityBackupFilter is for complex use cases when the cluster spreads multiple racks or availability zones [1] [2] - If you have multiple nodes per machine, consider RendezvousAffinityFunction.ExcludeNeighbors property [3] [1] https://ignite.apache.org/releases/latest/dotnetdoc/api/Apache.Ignite.Core.Cache.Affinity.Rendezvous.ClusterNodeAttributeAffinityBackupFilter.html [2] https://www.gridgain.com/docs/latest/developers-guide/configuring-caches/managing-data-distribution#backup-filter [3] https://ignite.apache.org/releases/latest/dotnetdoc/api/Apache.Ignite.Core.Cache.Affinity.AffinityFunctionBase.html#Apache_Ignite_Core_Cache_Affinity_AffinityFunctionBase_ExcludeNeighbors On Tue, Jun 27, 2023 at 4:02 PM <[email protected]> wrote: > Hi Pavel, > > > > We are running 6 node cluster with Active Active setup. 3 nodes in > one Datacenter and 3 in another datacenter with external cache > store enabled for some caches and native persistence enabled for > others.
