Clustering across co-locations

Elastic Stack Elasticsearch
1

Hi,

I'm currently evaluating ElasticSearch to see if it fits our needs. One
major requirement is to have our index available in 2
geographic co-locations, but also minimize the internet traffic between
these locations.

I want to be able to have ES clients in each location execute their queries
only on the nodes in the local network. Is there a way to configure the
cluster for this? This would require co-location's node set having each
shard or it's replica, and restricting where the query can run.

Is this possible to configure, and if so, how?

Thanks!

Hi Craig,

I think what you can do here is to split your data in two indices - one per
location - although you can easily search in both if you want to. Then,
keep each index within the limits of its location by Shard Allocation
settings:

After doing that, data shouldn't migrate between locations, and you could
enable clients to search only in one of the two indices.

Thanks Radu, that looks like exactly what I needed.
