Index Include Non Key Fields

At the risk of exposing my ignorance…

Does couchbase support or plan to support included fields for Indexing.

The basic idea being that we wish for certain fields to be available for pushdown predicates and to avoid fetching but also we don’t want them to effect the ordering of the index nodes?

if not, why not? (I assume it has to do with the dstorage structure)

Couchbase index keys similar like b-tree structure.
All the index keys are available for pushdown and ordering.

Include fields can be tracked through MB-27176. cc @binh.le
