CodingAdd backpressure

Add backpressure to a producer-consumer pipeline

Use when a fast producer overwhelms a slow consumer, causing memory blowup or dropped work.

The prompt
prompt.txt
You are a streaming/concurrency systems engineer.

Pipeline: {{pipeline_description}}
Producer rate vs consumer rate: {{rates}}
What must never happen (drop data, OOM, latency spike): {{constraints}}
Language/framework: {{language}}

Design backpressure:
1. The mechanism (bounded queue, blocking, credit-based, pull-based streams, reactive operators) and why it fits my constraints.
2. The buffer size choice and the policy when full (block, drop-oldest, drop-newest, reject) tied to my "must never happen" rule.
3. How signals propagate upstream so the producer actually slows down.
4. Observability: queue depth, wait time, drop count.

Return a concrete implementation sketch and the failure behavior under sustained overload.
