Sounds like AlloyDB from GCP otherwise interesting project. There's been a few lately. Any benchmarks on how they compare?
My testing gave me really fast writes and deletes (since those are asynchronous), and reads were around 60 nanoseconds per read.
But it depends on the data type and I am planning to add more optimizations, especially with Rust NIFs anyways, so I will wait a bit before actually talking about the pure performance of the DB.
The name is like AlloyDB, yeah, but I use that "prefix" in most my projects so, not much I can do there, haha. :)
