Hi all, We have a deployment scenario I can't seem to find any examples of, and any help would be greatly appreciated. We're running ElasticSearch in 3 AWS regions. We want these regions to survive a failure from other regions, and we want all writes and reads from our clients to occur in the local region. Rather than have 1 large cluster that spans 3 regions, I would like the ability to asynchronously replicate document creation and deletion across the regions. Our application creates immutable documents, so update semantics don't apply. Is there any way this can be accomplished currently? Note that I don't think a river will provide us with the partition we need since it is a singleton. Thanks!

You could use snapshot and restore, or even Logstash.

Hey Mark, We're looking for a solution that's faster than a snapshot+restore. We do follow an eventual consistency model, but we'd like the replication to be near realtime, so a snapshot and restore would be too slow. We really need something that synchronizes between regions with some sort of log or queue, so that if a region goes down, we can replay all missed operations. We were going to put an SQS queue in our application tier, but if this is something an ES plugin can provide, we would prefer to utilize that over writing our own. I was searching the plugin api, but I can't seem to find anything that will receive post document write/delete events I can hook into. Ideally, I would like each node to queue up changes to primary shards. This way, we can distribute sending the changes among all our nodes and we won't have a single point of failure.

Then you can look at leveraging Logstash with a broker (redis/rabbitmq), it'll do NRT and provides that queue. There may be other community based plugins that can do this, otherwise it's something you'd have to handle yourself.
