  7. SocketCluster

    Highly scalable realtime pub/sub and RPC framework

    Project mention: Exponential Rate Limiting | news.ycombinator.com | 2024-09-12

    For WebSockets, using SocketCluster (https://socketcluster.io), it's possible to queue up all requests from the same client and then detect and respond to high backpressure spikes (e.g. by disconnecting the client and/or recording the incident).

    You can combine different approaches like limiting the number of connections from a single IP within a certain timeframe and also limiting the backpressure.

    The ability to measure and respond to extreme backpressure spikes on a per-end-user basis is highly valuable because backpressure in SocketCluster takes into account the processing time of client requests.

    A common strategy that spammers use is to identify and invoke the most expensive endpoints in your system.

    A lot of people still don't understand the value proposition of being able to process requests from clients in-order. It's also really good at preventing race conditions and makes your environment highly predictable.
