State of cross-datacenter replication

Elastic Stack Elasticsearch
1

I am working for a company that needs cross-datacenter replication (Europe, Asia, US) with Elasticsearch clusters.

What I found so far is that it is not recommended. A requirement for replication across high latency networks are Sequence Numbers. When I look at a number of commits in 2017 there seem to be Sequence Numbers present.

So maybe someone can tell me if this feature is still in development? Is there a known roadmap for cross-datacenter replication?

Thanks in advance for any info.

We are actively working on it. Its work is tracked at https://github.com/elastic/elasticsearch/issues/30086

As of Elasticsearch 6.7.0, cross-cluster replication (what we call cross-datacenter replication) is available and production-ready in Elasticsearch. Check out our announcement blog post.
