  DoltgreSQL - Version Controlled PostgreSQL

  

> Why is Dolt MySQL flavored?

TLDR; Because go-mysql-server existed.

We have a Postgres version of Dolt in the works called Doltgres.

https://github.com/dolthub/doltgresql

We might have a go-postgres-server package factored out eventually.

  Dolt – Git for Data

  

Hi, this is my project :)

For us this package is most important as the query engine that powers Dolt:

https://github.com/dolthub/dolt

We aren't the original authors but have contributed the vast majority of its code at this point. Here's the origin story if you're interested:

• vitess

  60 17,834 9.9 Go

  Vitess is a database clustering system for horizontal scaling of MySQL.

  

With Vitess likely merging a lot of its binaries into a single unified binary: https://github.com/vitessio/vitess/issues/7471#issuecomment-...

... it would be a wild future if Vitess replaced the underlying MySQL engine with this as long as the performance is good enough.

• garnet

  4 9,063 9.3 C#

  Garnet is a remote cache-store from Microsoft Research that offers strong performance (throughput and latency), scalability, storage, recovery, cluster sharding, key migration, and replication features. Garnet can work with existing Redis clients.

  

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.
