What is stream backpressure?
Backpressure occurs when a data producer can generate data faster than a consumer can process it. Node.js streams provide mechanisms to prevent the producer from overwhelming the consumer. Properly handling backpressure helps control memory usage and keeps data flow manageable.
Key Takeaways
- Backpressure controls producer-consumer speed differences.
- It helps prevent excessive buffering and memory usage.
- Node.js streams provide flow-control mechanisms.
