WKafka, an open-source project, has released the 8th technical article in its series, focusing on preventing toxic messages from freezing a pipeline. The issue arises when a single malformed JSON causes a Kafka consumer to crash in production. WKafka addresses this by automatically isolating problematic messages in a Dead Letter Queue (DLQ).

This implementation allows for automatic routing of permanent failures to a designated DLQ topic, exponential backoff to prevent request storms, and zero blocking to ensure healthy messages continue processing. WKafka is compatible with Python 3.9 to 3.14 and is available on GitHub and PyPI.

We checked 53,709 production resources for backups. 61% had none.

Disclosure: I work at Eon, on the content side. Our team ran these assessments and this is our data. I didn't write the queries, but I sat with the engineer who did, and the methodology below includes what we couldn't see. Argue with it. Most backup tools produce a coverage report, and most of those reports work from tags.
