We engineered this zero-bloat Python 3.12+ / AsyncIO 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 a high-performance, concurrent Redis Streams consumer group worker
with a dead-letter queue (DLQ) for handling failed messages. The worker uses exponential
backoff with jitter to handle transient Redis connection errors and ensures bounded concurrency
to prevent overwhelming the Redis server.
To use this module, run the following command:
python -m ai_dev_tool_redis_streams_consumer \
--redis-host <redis_host> \
--redis-port <redis_port> \
--redis-db <redis_db> \
--stream-name <stream_name> \
--consumer-group-name <consumer_group_name> \
--dlq-stream-name <dlq_stream_name> \
--max-concurrency <max_concurrency> \
--max-retries <max_retries>
Example:
python -m ai_dev_tool_redis_streams_consumer \
--redis-host localhost \
--redis-port 6379 \
--redis-db 0 \
--stream-name my_stream \
--consumer-group-name my_consumer_group \
--dlq-stream-name my_dlq_stream \
--max-concurrency 10 \
--max-retries 5⚡ 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.
Click Launch Interactive Sandbox to execute the live demo harness directly in your browser terminal before spending a cent.
Immediately upon completing Stripe checkout, you are redirected to /download/ai-dev-tool-async-redis-streams-consumer-group-worker-with-dead-letter-queue-jq9flb for instant 1-click browser download, and a backup copy is dispatched to your email.
