Multi-region Elastic Cloud cluster?

Elastic Stack Elasticsearch
1

HI all,

Does Elasticsearch provide support for multi-region clusters? Say I deploy 2 clusters (one in each region) would I then be able to utilize both and have the cluster replicate the data between the two?

I was not able to find a definitive answer in the documentation. I did found a github issue concerning cross-cluster replication here: https://github.com/elastic/elasticsearch/issues/30086

Is that still the case or have new features been released in the meantime?

Cheers!

Yes, I think cross-cluster replication (CCR) is the feature you are looking for. It's currently at beta status but we are actively working on getting it ready for production use.

Splitting a single cluster across multiple regions does not work very well and is not recommended. Elasticsearch makes various assumptions that node-to-node connections are quite reliable and low-latency, and this isn't the case with cross-region connections.
