Redis is an open source (BSD licensed), in-memory data structure store, used as a database, cache and message broker. It supports data structures such as strings, hashes, lists, sets, sorted sets with range queries, bitmaps, hyperloglogs, geospatial indexes with radius queries and streams. Redis has built-in replication, Lua scripting, LRU eviction, transactions and different levels of on-disk persistence, and provides high availability via Redis Sentinel and automatic partitioning with Redis Cluster.

Are Free, Open-Source Message Queues Right For You?
A notable challenge with Redis Streams is that it doesn't natively support distributed, horizontal scaling. Also, while Redis is famous for its speed and simplicity, managing and scaling a Redis installation may be complex for some users, particularly for persistent data workloads.

Redis vs. KeyDB vs. Dragonfly vs. Skytable | Hacker News
1. Redis: I'll start with Redis which I'd like to call the "original" key/value store (after memcached) because it is the oldest and most widely used of all. Being a long-time follower of Redis, I do know it's single-threaded (and uses io-threads since 6.0) and hence it achieves lesser throughput than the other stores listed above which are multi-threaded, at least to some...
Memcached vs Redis - More Different Than You Would Expect
Remember when I wrote about how Redis was using malloc to assign memory? I lied. While Redis did use malloc at some point, these days Redis actually uses jemalloc. The reason for this is that jemalloc, while having lower peak performance has lower memory fragmentation helping to solve the framented memory issues that Redis experiences.

This blog looks specifically at performance, however there is...

  • Essential guide to WebSocket authentication
    Of course, if this all sounds like a headache, you might consider Ably. Apart from solving the authentication problem, Ably provides additional features you’d need to implement on top of WebSockets like Presence and message queues, and provides production guarantees that will be time-consuming or costly to achieve on your own like 99.999% uptime guarantee, exactly-once delivery, and guaranteed message ordering. - Source: dev.to / 5 months ago

  • Cursor Everywhere: An experiment on shared cursors for every website
    A realtime protocol like WebSockets seemed like a logical way to share real-time updates of cursor positions. Working at Ably, it was a no-brainer to use it as my WebSocket-based pub/sub broker. A pub/sub broker simplifies many aspects of projects like this, often coming with built-in features that speed up development. For instance, I wanted each browser's cursor position to be continually available to other... - Source: dev.to / 9 months ago
