Redis Re-Implemented with SQLite
I've used SSDB[0] in the past for some really stupid large datasets (20TB)_and it worked really well in production

- The first version of Redis, written in Tcl
-
Building a distributed task queue in Python
> Or wanting to shift the architecture entirely to avoid using memory-bound Redis as a queue with an overflow risk.
I wanted to use SSDB[1] instead of Redis for that reason, but it doesn't support the necessary data structures.

- I deleted 78% of my Redis container and it still works

Tell HN: Memcached and Redis Considered Harmful
It's 2021 and we have extremely fast key-value lookups using LevelDB/RocksDB, but we're still using RAM-based caching tools [1] [2] [3]. It's time to consider RAM-based caching harmful, and start caching with SSDs for larger datasets and lower costs. For ex: SSDB [4]

Using a disk-based Redis clone to reduce AWS S3 bill
Aside from this particular use-case, which is what most people here are talking about -- I had never heard of the SSDB project, but it interests me because I often use Redis for certain things it's able to do, aside from its in-memory storage, and sometimes the fact that the data is not stored on disk is a bit of a drawback for me, something I have to work around.

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.

Node.js server-side authentication: Tokens vs. JWT
In server-side authentication, the session state is stored on the server-side, which can be scaled horizontally across multiple servers using tools like Redis or Memcached.
What are some alternatives?
KeyDB - A Multithreaded Fork of Redis
Varnish - The project homepage
kvrocks - Apache Kvrocks is a distributed key value NoSQL database that uses RocksDB as storage engine and is compatible with Redis protocol.
node-cache - A simple in-memory cache for nodejs
Tendis - Tendis is a high-performance distributed storage system fully compatible with the Redis protocol.
dragonfly - A modern replacement for Redis and Memcached
mini-redis - Incomplete Redis client and server implementation using Tokio - for learning purposes only
node-cache - a node internal (in-memory) caching module
dynomite - A generic dynamo implementation for different k-v storage engines
memKeyDB - MemKeyDB is a fork of Redis, adjusted to store objects on both Intel Optane Persistent Memory and DRAM.
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.
