Ask HN: A memory efficient and concurrent redis – are you interested?

Posted by qkhhly on Sunday February 26, 2017 @12:18AM
from the ask-hn dept.

We are working on a redis-compatiable key-value store. Our design reduced memory consumption by half for the same dataset compared with redis. We also implemented multi-threading and ACID compliance. In a 16-core machine, we achieved more than 10X throughput compared to redis. Our implementation is 100% compatible with redis clients (it can be used as a drop-in replacement of redis). We would like to gauge the interest in our product. Please leave a comment if you would like to try it out or if you have additional feature requests.

I want to try as well. I'm curious, (if you don't mind sharing this information) what language is used to develop this new technologie ?

It's developed in C++. We have considered Go, but one of the major goal we want to achieve always non-blocking. Go can be blocked by GC, and redis maybe frequently blocked by fork/heavy commands.

Are there Jepson results?

Seems an interesting tool. The only question is how effective it is. But we should definitely try it out.

Over the past few years, Jepsen has developed a reputation within the database community for having an ability to verify claims about databases.

it would be nice if there is possible to "move" values to somewhere else -- on other type of persistence in case of eviction, or simply write on a file in the simplest form -- just an idea

Does it include pub/sub?

We have implemented the core features. Pub/sub is on our todo list. Is pub/sub a critical feature to you? If we support pub/sub, what would be your motivation/obstacle to switch to our product?

I'm currently using redis in a pair of applications, one of which also uses pub/sub. I have many other applications which would benefit from the caching layer that redis provides, and since they currently have none there really isn't an obstacle to testing another solution.
