Ably
SocketClusterBased on our record, Ably should be more popular than SocketCluster. It has been mentiond 26 times since March 2021. We are tracking product recommendations and mentions on various public social media platforms and blogs. They can help you identify which product is more popular and what people think of it.
During this weekโs AWS us-east-1 outage, Ably maintained full service continuity with no customer impact. This was our multi-region architecture working exactly as designed; error rates were negligibly low and unchanged throughout. Any additional round trip latency was limited to 12ms, which is below the typical variance in any client-to-endpoint connection, and well below our 40โ50ms global median; this is... - Source: dev.to / 9 months ago

Ably is a real-time infrastructure platform that focuses on delivering low-latency, reliable messaging across global distributed systems. It's designed for developers building event-driven applications, including chat, but also supports broader use cases like live dashboards, GPS tracking, and collaborative tools. - Source: dev.to / about 1 year ago
For our web socket-based application, weโll be using Next.js and Ably, a service that allows us to easily integrate and manage real-time capabilities in our apps powered by web socket. - Source: dev.to / over 1 year ago
Ably offers various solutions for developers, with their most popular being realtime messaging based on the pub/sub model. When you publish a message to a channel, all devices connected to that channel receive it instantly. - Source: dev.to / over 1 year ago
This is basically the principle behind https://socketcluster.io/ scalability; the sharding of channels across available brokers is pseudo-random. It uses a hash function for determinism but the distribution looks essentially random. - Source: Hacker News / about 1 month ago
I started building something pretty obscure about 14 years ago; https://socketcluster.io/ an open source, WebSocket-based RPC + pub/sub library with a focus on in-order async stream-processing with backpressure monitoring. It didn't start out like that. Initially, it was just another WebSocket library with a focus on making it easier to scale to multiple processes. It's kind of mind-bending to me though that it... - Source: Hacker News / about 2 months ago
I've been advocating for this approach for years. You can't avoid race conditions without using some kind of queueing mechanism and you need backpressure to measure queue capacity. I built this into every aspect of https://socketcluster.io/ - From pub/sub channels, RPCs to event listeners. - Source: Hacker News / about 2 months ago
It's interesting reading this. Preventing these kinds of concurrency issues is exactly why I built https://socketcluster.io years ago. Though it solves the problem at the app layer rather than the storage layer. But not many developers care about these race conditions it seems. It's not just an issue with SQL but a more general issue with coding. This is a great example because it shows how concurrent executions... - Source: Hacker News / 2 months ago
Https://socketcluster.io/ has had such stream implementation and backpressure management since at least 2019;. https://github.com/SocketCluster/writable-consumable-stream. - Source: Hacker News / 5 months ago
