I have two nodes, and would like to define one index with 2 shards that are both primary and replica of each other.
In other words, on node1 will be the first shard, on node2 the second shard.
Each time a document will be physically stored on the shard on node1, it will clone itself to the shard on node2, and vice versa.
I want to do it for load balancing.
I couldn't find how to do it in the documentation.
Is it even possible in Elastic?
