My question is with reference to elasticsearch's new feature 'cross cluster search' https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-cross-cluster-search.html
Are there any performance tests/ studies available for this feature? How scalable is it?
One use case we have is, 10 clusters with 1 million documents each (total 10 mil across all clusters)
(need to support pagination, any column search, and sorting)
Is elastic search good fit for this scenario?
