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.

Getting both a mutable and immutable reference to a shared structure?
Another option I can think of - but not completely sure how one would implement in Rust - would be to never mutate the shared state, but rather when updating it - completely swapping it out with a completely new copy of the desired state. There's lots of different ways to go about doing this - each with their own trade offs. But using some form of Persistent Data Structure would probably be a good way to start. If you only have a single writer - then I believe using a Cell and simply updating which version of the structure is being read could work. rpds seems to be a decent start to look at these sorts of structures in Rust.

Learning Clojure made me return back to C/C++
Thanks for taking the time to provide a detailed response. Need to think on this. I had actually started a regular Clojure parser using LLVM as a hobby, but then my friend said it was better to implement this in a safe-memory and. save-concurrency language like Rust and leverage cranelift for code generation. So, now I am learning rust, lol. (Btw, Rust has a persistent data structures lib too: https://github.com/orium/rpds )

Persisting data that has revisions for values
Take a look at https://github.com/orium/rpds or one of the many others.

SableDb – a key/value store that uses RocksDB and Redis API (written in Rust)
a few times, seems interesting. The author's also built a lot of other cool concurrency primitives for Rust as well.

Is Something Bugging You?
- Dropbox [3] uses a similar approach but they talk about it a bit more abstractly.
Sans-IO is more documented in Python [4], but str0m [5] and quinn-proto [6] are the best examples in Rust I’m aware of. Note that sans-IO is orthogonal to deterministic test frameworks, but it composes well with them.
With the disclaimer that my opinions are mine and mine alone, and don’t reflect the company I work at —— I do work at a rust shop that has utilized these techniques on some projects.
TigerBeetle is an amazing example and I’ve looked at it before! They are really the best example of this approach outside of FoundationDB I think.

Production grade databases in Rust
There is a valid argument to be made for threads over async in a large percentage of use cases where async is considered the default. If this is what you are referring to however, I don't think they ever referred to async as completely useless: https://github.com/spacejam/sled/issues/1123.

Best local database that works on all platforms including web?
Have you looked into other pure-Rust databases as well, such as sled or GlueSQL which has an SQL interface on top of sled? I wonder how those would compare to Persy.

Are there any embedded databases that have multiple-process support?
I'm not sure what you need. Are these of any use? https://github.com/meilisearch/heed https://github.com/spacejam/sled

Are there a demand for management system of embedded storage like RocksDB? I plan to build one in Rust as the language becoming a core of many popular databases but wonder if there’s a demand. Can’t find any similar project even in other languages.
There is also Sled but as I understand it that is being reworked to use the author's new DB core Marble

GreptimeDB: a new open source database designed for large-scale time-series data storage and processing, written in rust
There are some databases like sled/FlashDB designed to be embedded to other applications even bare metal microcontrollers. But I do doubt the potential bussiness value of a pure embedded database.

Ask HN: Serverless” key value store with transactions?
https://github.com/spacejam/sled
To add transaction support, you probably need a good understanding of how the memtable works in Log Structured Merge trees:
What are some alternatives?
hypergraph - Hypergraph is data structure library to create a directed hypergraph in which a hyperedge can join any number of vertices.
RocksDB - A library that provides an embeddable, persistent key-value store for fast storage.
moodycamel - A fast multi-producer, multi-consumer lock-free concurrent queue for C++11
rust-rocksdb - rust wrapper for rocksdb
redis-rs - Redis library for rust
cranelift - Cranelift code generator
sqlx - 🧰 The Rust SQL Toolkit. An async, pure Rust SQL crate featuring compile-time checked queries without a DSL. Supports PostgreSQL, MySQL, and SQLite.
