We have a usecase in our projects, where elasticsearch is used for search and need to send anywhere from 50,000-100,000 documents for further processing and then send to client.
The response document should contain minimally 1 field (document IDs) alone from elasticsearch.
With HTTP REST Client , we were able to transfer in 10+secs. Is it possible with any other ways to
transfer at-least 50,000 documents in < 1sec ?
