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 asynchronous Redis streams consumer group worker with a dead-letter queue.
It utilizes the Redis Streams data structure to provide a high-performance, fault-tolerant, and scalable solution.
The worker consumes messages from a Redis stream, processes them, and acknowledges the messages.
If a message fails processing, it is moved to a dead-letter queue for further analysis.
The module uses bounded concurrency to prevent overwhelming the system with too many concurrent tasks.
It also implements exponential backoff with jitter to handle transient failures.
Usage:
python -m ai_dev_tool --redis-host localhost --redis-port 6379 --stream-name my_stream --group-name my_group --consumer-name my_consumer
Configuration:
The module uses the following configuration options:
--redis-host: The hostname or IP address of the Redis server.
--redis-port: The port number of the Redis server.
--stream-name: The name of the Redis stream.
--group-name: The name of the consumer group.
--consumer-name: The name of the consumer.
--concurrency: The maximum number of concurrent tasks.
--dead-letter-queue: The name of the dead-letter queue.
