Describe the question in detail
Our requirement is for a Federated search across clusters means executing a single query that is transparently fanned out to multiple independent clusters (e.g. regions, shards, tenants), and their partial results are aggregated (merged, sorted, deduplicated) before returning a unified response.
And this was answered in this issue #72
Question:
How to setup the Central VTSelect to point to other 10 clusters which have VTStorage running....
-storageNode=vtselect-addr-in-cluster-1,vtselect-in-cluster-2...., vtselect-in-cluster-10
Note that the addr here could be the load balancer in front of the (edge) vtselects.
Reference in the Other ticket:
If you're using our Operator, you can set extraStorageNodes in here as well for the same result.
When I setup the VTSelect in the Central cluster, After I add this change
-storageNode=vtselect-addr-in-cluster-1,vtselect-in-cluster-2...., vtselect-in-cluster-10
How do I pass the Credentials to authenticate the downstream edge VTSelects? ...
