Answer
Backpressure occurs when consumers can't keep up with event producers.
Solved via throttling, buffering, or rate limiting.
Quick Answer
Backpressure is when a consumer signals to the producer to slow down because it can't keep up. Without backpressure, the consumer's queue fills up and crashes. Solutions: bounded queues (block or drop when full), reactive streams with explicit demand signaling, circuit breakers that stop publishing when queues are full, or auto-scaling consumers to match producer rate.
