I have an index named DataIndex. It has two types: posts and users. The posts have an user which has small info like just id, name but it has more. And I regulary update users some fields like followers count,age etc . So I must do below jobs: - When I run on posts type, I want to join users. - I want to join user's posts. So I can retrieval that the user has 1000 data etc. You can suggest using Nested Objects or Parent/Child object. But I regulerly update users therefore I can't use nested objects. Parent-Child has a cost in terms of performance and memory used. I want to know is there any method doing this jobs with high performance. -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
