Hi, I'm wondering if ES supports a multi-master configuration over WAN. Let's say I have node A and node B and they're in different parts of the world. Can I write to the instance closest to my location and have the data automatically replicated to the other? Reading through the cluster configuration docs, it wasn't quite clear if this was possible.

It's possible but not recommended due to the latency in timings, this has negative impacts on the cluster state and can exacerbate split brain potentials.

Matthew, Multi-master over WAN is not supported. Typically in this case you would modify your ingestion pipeline to double write to both clusters. If you want to query across both clusters simultaneously take a look at the tribe node [1]. Note that if all you want is to have the data available as a backup, you can use snapshot/restore to an S3 bucket [2]. Cheers.
