This looks very interesting, however I'm concerned about some of the implementation details...

1. It mentions using secondary indexes - its my understanding thats a huge no-no, as they have to hit the whole cluster 2. Uses "lightweight" transactions - also another perf hit, as lightweight transactions have (anecdotally) a 6x slowdown...

I like the idea but I'm curious if these are issues and whether these uses are something the author is looking to replace...

Very interesting idea though!
