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.

- Skytable NoSQL Database: Even with BlueQL, Skytable Outperforms Redis and KeyDB
- So, you call yourself the fastest key/value store? It's 5X, 10x and 25X faster

Skytable: A NoSQL database project in Rust about 10X faster than Redis
UPDATE: I have published some initial benchmarks against KeyDB here: https://github.com/ohsayan/sky-benches. Oddly enough, the bump in the number of queries in KeyDB is similar to that of Skytable. If anyone has suggestions or find something to be anomalous, please open an issue!

Best engineering interview question I've gotten
> Multiple clients racing can't be fixed.
Really? You can't think of a single way for multiple clients to operate on the same data without racing? (Here's a hint if you're still having trouble: https://github.com/memcached/memcached/wiki/Commands#cas.)

How to choose the right type of database
Memcached: A simple, open-source, distributed memory object caching system primarily used for caching strings. Best suited for lightweight, non-persistent caching needs.

Sieve is simpler than LRU
Oh, thank you! I didn't realize that LRU Maintainer Thread was more than an expiration reaper. When it was first being introduced that was its first responsibility as lazy expiration removal by size eviction meant dead entries wasted capacity. It was all work in progress when I had read about it [1] and talked to dormando, so it got fuzzy. The compat code [2, 3] might have also thrown me off if I only looked at the setting and not the usage. Its a neat variant to all of these ideas.

Django Caching 101: Understanding the Basics and Beyond
Django supports using Memcached as a cache backend. Memcached is a high-performance, distributed memory caching system that can be used to store cached data across multiple servers.
What are some alternatives?
skytable - Skytable is a modern scalable NoSQL database with BlueQL, designed for performance, scalability and flexibility. Skytable gives you spaces, models, data types, complex collections and more to build powerful experiences
Varnish - The project homepage
KeyDB - A Multithreaded Fork of Redis
node-cache - A simple in-memory cache for nodejs
dragonfly - A modern replacement for Redis and Memcached
MapDB - MapDB provides concurrent Maps, Sets and Queues backed by disk storage or off-heap-memory. It is a fast and easy to use embedded Java database engine.
node-cache - a node internal (in-memory) caching module
oxigraph - SPARQL graph database
RocksDB - A library that provides an embeddable, persistent key-value store for fast storage.
Redis - Redis is an in-memory database that persists on disk. The data model is key-value, but many different kind of values are supported: Strings, Lists, Sets, Sorted Sets, Hashes, Streams, HyperLogLogs, Bitmaps.
