ImmuDB v1.3.0 – fastest immutable database in Go (github.com)

I'm not affiliated with ImmuDB but I really love what they have created here!

My favorite features:

- Crazy performance (1M inserts per second on 4 cores with SSD)

- S3 storage

- Interesting features around immutability / versioning

- Apache 2.0 license

I can't wait for Compression (on the roadmap)
