How can I set X-opaque-Id to header when searching?

[ryook]

I want to set X-opaque-Id to header to track task.
There is API in elasticsearch, Can't I use it using this library?

+1. I was wondering the same. How to set this in python elasticsearch library?

es = Elasticsearch(["http://localhost:9200"], headers={"x-opaque-id": "123456"})
res = es.search(...)

This has been fixed in #1135, can be set per API request or on the client like so:
This will be available in elasticsearch>=7.6.0.

es = Elasticsearch(..., opaque_id="app-1")
es.search(..., opaque_id="request-2")
