-----------------------------------------

Thanks Filipe, this optimization has been on my TODO list for too long.  The same technique can be applied to _all_docs?include_docs=true for what it's worth.

> More efficient _changes?include_docs=true

> When using the changes stream with the option include_docs set to true, after having the #doc_info record of a document, we open the document by its ID instead of using the #doc_info record. This is not optimal since opening the doc by its ID implies traversing the by-id B-Tree to find a #full_doc_info record and to finally convert it into a #doc_info record.
> The following patch fixes this.
