Understanding the Plan of Query

Hi, @vsr1 Can you tell me what is the Stream part of the plan does?? attaching a screenshot of one of my queries.

And please can you share some doc to read about the plan of couch-base queries, tried finding it on the couchbase documentation site but unable to do so.

The stream operator is responsible for taking each document and streaming it back to the client via the network pipe.
It basically does the work of taking the document in internal format, marshal it back to a stream of bytes and write the bytes to the pipe.
