Hi,
To make sure that two nodes on the same host don’t have primary and backup
versions of the same partition you can use
cacheConfiguration.setAffinity(new RendezvousAffinityFunction(true));
See
https://ignite.apache.org/releases/latest/javadoc/org/apache/ignite/cache/affinity/rendezvous/RendezvousAffinityFunction.html
for details
(note the excludeNeighbors parameter).

Subject: Is backup copy always stored on different host - is it
host-awarereplication
Hi
Using ignite 2.3
When we use backup as 1, does it mean that backup copy is store in another
host
Lets say, if we have cluster with 3 hosts H1, H2, H3, each host running 2
ignite nodes
H1 is holding the primary copy, backup copy should be on H2 or H3, it should
not be on H1, but on different node.
Is it host-aware replication ??
Thanks
Naveen
