rave-level is shaping up, iterating (as a follower) at twice the speed of level-party, bringing it closer to classic-level:

Published many-level.

@vweevers any indication on many-level vs local redis perf?

[vweevers]

Depends on what functionality you need. Without iterators, simple GET and SET commands suffice and can easily be benchmarked against Level modules. For iterators, you need hashes and/or sorted sets, or perhaps Redis Streams which I'm not familiar with, but either way the performance characteristics will be different. Buffer support will slow it down. Etc.

I got side tracked by a Node.js bug on Windows (https://github.com/nodejs/node/issues/42496) but that seems to be an edge case so I went ahead and published rave-level.
