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.

The One Billion Row Challenge in CUDA: from 17 minutes to 17 seconds
> GPU Hash Table?
How bad would performance have suffered if you sha256'd the lines to build the map? I'm going to guess "badly"?
Maybe something like this in CUDA: https://github.com/Cyan4973/xxHash ?

NIST Retires SHA-1 Cryptographic Algorithm
If you're only using the hash for non-cryptographic applications, there are much faster hashes: https://github.com/Cyan4973/xxHash

[Study Project] A memory-optimized JSON data structure
But what's the catch, you're thinking ? Well, it is a bit slower than its counterparts when it comes to deserializing (and marginally faster for serializing). To achieve smaller footprint, it uses a few tricks and notably a custom hash table to deduplicate strings. This comes at a cost of course (even when featuring xxHash to speed things up), but keeps the slowdown reasonable (I think).

What do you typically use for non-cryptographic hash functions?
Non cryptographic hashes has collisions, for example, assume you having content like "abcdefg" which hashed value is "123", in case of weak hash algorithm some other content like "abcdefZ" can also have a hash "123" which basically means such hash function is failed to be unique fingerprint of particular content. BLAKE3 for example can do 6-7Gb/s which make it pretty fast and secure. If your requirement accepts collision with defined error rate, I would advise you to take a look at XXH3 if you need very snappy hash algorithm, which can run at pace or RAM access (30GB/s+), but again, run tests at particular equipment you targeting, may be AES hardware accelerated MeowHash will serve you better.

Valkey Is Rapidly Overtaking Redis
One of the challenges Redis labs here have is that there's very little reason for their userbase to stay loyal to them.
antirez retired from Redis development a few years ago.
From https://github.com/redis/redis/graphs/contributors it looks like activity since he left has been mostly from people who didn't overlap with him much.
Redis Labs have not shown themselves to be outstanding stewards of the project as far as I can tell. Why shouldn't people support the fork?
