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.
