Backpressure and Message Batching
Prevent fast producers from overwhelming slow consumers using backpressure signals and message batching over WebSockets.
The Problem of Speed Mismatch
When a producer sends faster than a consumer or the network can handle, messages pile up in buffers, memory grows, and latency spikes. Managing this is called backpressure.
The Send Buffer
Each WebSocket has an outgoing buffer. If you keep calling send faster than the socket can flush, that buffer grows unbounded.
