[SableDb]

It performs better and uses different design choices (for example: SableDb uses tokio's local task per connection, and in general it uses green threads to make the code more readable and easy to maintain).

I will release some design documents later on (hopefully this month). Remember that is a one man project (hopefully, not for long), so it takes time to organize everything :)

I did some rookie testing between KVRocks and sableDB using Redis Benchmark

KVRocks

SableDB

KVRocks seems faster but certainly not a bad start

[SableDb]

Sharing the build configuration (e.g. did you make sure to build `sabledb` in release mode?) + threads configurations etc, worth mentioning.

How well does raw Redis and/or raw RocksDB perform on your machine?

[theossuary]

I like the idea of doing thread local execution of Tokyo tasks; I assume that means SableDb is mostly single threaded? Was this to reduce complexity, or for some other reason? I'm looking forward to the design doc on this!

[SableDb]

It is multi-threaded (configurable, you can set it to a specific number configuration file, or use the magic value 0 where SableDb decides based on the number of cores divided by 2).

Each incoming connection is assigned to a worker thread, and two tokio tasks are created for the connection (one for reading and another for writing).

Using tokio allowed me to use the `async` code without using "callback hell" so the code looks clean and readable in a single glance without the need to follow callbacks

Hi SableDb. I am looking for a tech cofounder in databases. Probably not the best place to ask for a cofounder. :-) Regardless, would you be interested?

[scottlamb]

You might as well post it to the discussion of this article about why you won't find a technical co-founder. <https://news.ycombinator.com/item?id=39902372>

[vlovich123]

I’m potentially interested in a cofounder for my DB. Can you ping me on gmail to connect (username in profile)?
