I am upgrading ES 2.4 to 7.6.
Previously I had two different types in ES 2.4, say A and B. 'A' was parent and 'B' was child.
Now, what would be the best way maintain this relationship in ES 7.6?
Possibilities I came to figure out:
- Use Join?
- Use parent/child inside a document(since 7.6 is type-less)?
- Or are there any other new techniques?
Open to any comment or suggestion. An elaborated answer would be appreciated.
Thanks in advance
