We engineered this zero-bloat Cloudflare Workers / TypeScript blueprint to enforce bounded concurrency, deterministic exponential backoff with jitter, strict schema validation at the ingestion boundary, and structured JSON telemetry—ready to drop into production without weeks of plumbing.

"""AI Dev Tool: Async Redis Streams Consumer Group Worker with Dead-Letter Queue.
This module implements an async Redis streams consumer group worker with a dead-letter queue.
The architecture consists of a single worker process that consumes messages from a Redis stream,
processes them, and acknowledges or moves them to a dead-letter queue in case of failures.
Bounded concurrency is achieved through the use of async tasks with a limited number of worker tasks.
CLI usage:
python -m ai_dev_tool --redis-host <host> --redis-port <port> --redis-stream <stream> --redis-group <group> --redis-consumer <consumer> --dead-letter-queue <queue>
Configuration:
The module uses a typed configuration with strict validation.
The configuration consists of the following parameters:
- redis_host: The hostname or IP address of the Redis instance.
- redis_port: The port number of the Redis instance.
- redis_stream: The name of the Redis stream to consume from.
- redis_group: The name of the Redis consumer group.
- redis_consumer: The name of the Redis consumer.
- dead_letter_queue: The name of the dead-letter queue.
Error handling:
The module uses exponential backoff with jitter to handle transient errors⚡ Instant browser download upon Stripe redirect • 🛡️ Permissive MIT Commercial License

Enter your developer email to receive the runnable starter module for AI Dev Tool: Async Redis Streams Consumer Group Worker with Dead-Letter Queue plus our Tuesday digest of high-concurrency Python & Cloudflare Worker patterns. Zero spam, 1-click unsubscribe.
Raw LLM output takes multiple iterations, frequently hallucinates deprecated SDK methods, and omits bounded concurrency, backoff jitter, and CLI harnesses. For $5 (less than 4 minutes of engineering payroll), you get a pre-verified, sandbox-tested module you can drop straight into production.
