Description

I have been looking into adding an option into the iterator but it does look non-trivial.

Before the release of 3.0.0-0 I had been using my own createReadStream from within hyper-graph-db - https://github.com/e-e-e/hyper-graph-db/blob/master/lib/hyperdbModifier.js. It returned keys in reverse order to which they were added by the user. Thinking about it - I am not sure if this is 100% important but still wanted to raise it as a potential enhancement.

Research direction

Start by locating the createReadStream iterator in hyperdb and compare its behavior with lib/hyperdbModifier.js in hyper-graph-db. Determine how insertion order is represented and where an option could be introduced. Done means createReadStream can optionally return nodes in reverse insertion order without changing its existing default behavior, with coverage for both orders.
