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.

Experiences with Concurrent Hash Map Libraries
growt shows impressive benchmark results in this paper compared to folly, TBB, junction, and libcuckoo. However, it was not in good shape to be used as a production dependency. I had several issues and compilation errors here, here, and here.

A MySQL compatible database engine written in pure Go
You would be surprised by performance of modern .NET :)
Writing no-alloc is oftentimes done by reducing complexity and not doing "stupid" tricks that actually work against JIT and CoreLib features.
For databases specifically, .NET is actually positioned very well with its low-level features (intrisics incl. SIMD, FFI, struct generics though not entirely low-level) and high-throughput GC.
Interesting example of this applied in practice is Garnet[0]/FASTER[1]. Keep in mind that its codebase still consist of un-idiomatic C# and you can do way better by further simplification, but it already does the job well enough.

FoundationDB: A Distributed Unbundled Transactional Key Value Store
A vaguely similar project that might be of interest is: https://github.com/microsoft/FASTER
It's also an "unbundled" low-level component that one could use as the foundation for a database engine or whatever. According to Microsoft, FASTER is not just "fast", but significantly faster than even some basic in-memory data structures that ship in the .NET standard library!
The downside is that it doesn't (yet) support some more advanced features like multi-server distributed mode.
However, that relative simplicity may be preferred in some scenarios...

Event Sourcing
Last time i looked into it there weren't that many i could find. There is https://github.com/tikv/tikv which uses rocksdb with raft. and there is faster https://github.com/microsoft/FASTER/ .
