Per-message Kafka worker with crash recovery in Python
How a Redpanda-fed Python worker collapses head-of-line blocking and crash-resume into straight-line generator code by treating each message id as a durable promise id.
A Redpanda consumer kicks off one durable workflow per message and returns immediately. Each step is a checkpoint; a worker crash mid-deletion resumes from the last completed batch, and the record id deduplicates retries.
