Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Software Transactional Memory (1997)
I've been working on a JS database to support optimistic concurrency control. I did some research and arrived on 2 seemingly related concepts but from independent research lines. Software transactional memory in functional programming/Haskell land versus snapshot isolation in database research.
After reading them both, I asked this unanswered question on SO: https://stackoverflow.com/q/72084071/582917. My theory is that STM is the same as SI, but most SI database implementations don't just do value comparisons, but actually check a logical timestamp. This is probably done for performance reasons as databases handle larger pieces of data than functions would when using STM.
Along the way I also discovered SSI serializable snapshot isolation but it isn't yet available in rocksdb but cockroachdb apparently has a fork of rocksdb with it but I couldn't find it.
Anyway the db library which wraps around rocksdb is available to be used embedded in any nodejs program at https://github.com/MatrixAI/js-db.
What are some alternatives?
