I saw some mention of plans for geographic datacenter replication in the 1.0 release blog post, but no follow up. Was that feature implemented? If not, is it still on the roadmap? Is there a reliable way people have been handling that in the application layer?
I’m not sure about this feature in the 1.0 roadmap. Release 21.03 adds something called
learner nodes, which are nodes that are able to connect to a Dgraph cluster and replicate data, but do not vote on proposal.
When combined with best effort queries (and disabling mutations on that node), you could use such nodes as a read replica.
I don’t have a timeline for this on Cloud.
