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.

- 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.

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!

IceFireDB：Distributed disk storage database based on Raft and Redis protocol.
There is a project called Tendis, the architecture of IceFireDB is different from it, but they are all based on disk storage and resp protocol. Thank you for your attention and contact at any time

KeyDB CEO Interview: Getting into YC with a Fork of Redis
Does anyone have any experience with these other Redis clones? I need to write a benchmark on these someday (the outline for the blog post is already written), but have restricted my yak shaving recently:
- https://github.com/Tencent/Tendis
- https://github.com/Netflix/dynomite
On a separate note, is FLASH supposed to be an acronym? I can't tell if they're referring to flash storage (SSD, NVMe) or they're referring to perhaps a special algorithm that uses flash storage +/- some other features, or some altogether proprietary hardware.
What are some alternatives?
mini-redis - Incomplete Redis client and server implementation using Tokio - for learning purposes only
SSDB - SSDB - A fast NoSQL database, an alternative to Redis
keydb-operator - A KeyDB (Drop-In Alternative to Redis) Operator for Kubernetes
dragonfly - A modern replacement for Redis and Memcached
tikv - Distributed transactional key-value database, originally created to complement TiDB
incubator-kvrocks - Kvrocks is a distributed key value NoSQL database that uses RocksDB as storage engine and is compatible with Redis protocol.
IceFireDB - IceFireDB is a database built for web3 and web2. It strives to fill the gap between web2 and web3 with a friendly database experience, making web3 application data storage more convenient, and making it easier for web2 applications to achieve decentralization and data immutability.
memKeyDB - MemKeyDB is a fork of Redis, adjusted to store objects on both Intel Optane Persistent Memory and DRAM.
sled - the champagne of beta embedded databases
dynomite - A generic dynamo implementation for different k-v storage engines
