  • AWS us-east-1 outage: How Ablyโ€™s multi-region architecture held up
    During this weekโ€™s 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 40โ€“50ms global median; this is... - Source: dev.to / 9 months ago

  • Flat Datacenter Networks at Scale
    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
  • Doing Something That's Never Been Done Before
    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
  • Backpressure is all you need
    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
  • SQL: Incorrect by Construction
    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
  • We deserve a better streams API for JavaScript
