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.

Videohash ā Perceptual Video Hashing Package
The lack of the ideal solution is why I'm building Emdrive, an RDBMS with first class support for similarity search, based on indexing with an M-tree variation. Still very early stages ;) https://github.com/Twixes/emdrive

SableDb ā 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 Iām 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 donāt reflect the company I work at āā I do work at a rust shop that has utilized these techniques on some projects.
TigerBeetle is an amazing example and Iāve 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 thereās a demand. Canāt 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: Serverlessā 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:
