Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.
KeyDB
- I deleted 78% of my Redis container and it still works

So, you call yourself the fastest key/value store? It's 5X, 10x and 25X faster

Global Presence; I made a thing
KeyDB is a fork of (everyone's favourite cache store) Redis, and it's messaging protocol and API is 100% compatible with Redis. What that means is you can just point any Redis client (like Hiredis or redis-rb) at a KeyDB instance, and it'll Just Work™️, with no changes required. The KeyDB selling points are: 1) multi-threading by default, and a lot of work was ploughed in to high performance around multi-threading in KeyDB, 2) compatible with all the features of regular Redis, 3) some advanced features which Redis only offers in it's paid/enterprise version are included for free in KeyDB, and the big one for me is multi-active replication, which is what I'm playing with here.

A KeyDB Operator for Kubernetes
KeyDB is a multithreading, drop-in alternative to Redis. Keydb-operator easily creates a standalone (1 replica) or a multimaster (3 replicas) KeyDB in-memory database. When KeyDB is in multimaster mode, it is possible to have more than one master, allowing read/write operations to all them. That helps for high availability and fault tolerance.

p.s. another share-worthy Redis alternative is KeyDB https://github.com/EQ-Alpha/KeyDB

KeyDB CEO Interview: Getting into YC with a Fork of Redis
I went through the wiki, certainly it was interesting. I believe the implementation is at fastlock.cpp [0], I will go through it. You said earlier:
> If we spin too long the thread will sleep although we wait much longer than any other lock you’ll find.
Did you do any tweaks to mitigate this?
> Generally speaking you don't want to be dealing with this stuff unless you really have to.
Ofcourse. I am just way too curious and excited to learn about these!

It will be in 2027 and, unless you plan to run a SaaS that sells Dragonfly (like AWS), then it's Open Source for you today. (The license is Business Source License[0])

GitHub - dragonflydb/dragonfly: A modern replacement for Redis and Memcached
Not sure because of their weird BSL license : restricted use until 2027, then turn to an Apache license.
