Great Stack to Doesn't Work #2 — Kafka: "Where Did My Messages Go?"

May 30, 2026 · 9:44 PM UTC ·9 min read · 0 reactions · 0 comments · 35 views

TL;DR · WeSearch summary

The article discusses common issues faced by engineers using Kafka, particularly regarding message visibility and consumer lag. It emphasizes the importance of monitoring lag per partition to avoid stale data and highlights the problem of rebalance storms that can disrupt processing. Solutions such as dead letter queues and adjusting timeout settings are suggested to mitigate these challenges.

Key facts

▪Kafka does not lose messages but can hide them due to configuration issues.
▪Consumer lag should be monitored per partition to identify stuck consumers or problematic messages.
▪Rebalance storms can occur when Kafka mistakenly declares a consumer dead, leading to repeated disruptions in processing.
