I built a small Quarkus 3.39.4 app to check MDC across async calls. With ThreadContext.withContextCapture(), the common-pool continuation still read null. Returning it to the saved Vert.x request context restored the ID; the external stage's own MDC stayed empty. The tutorial includes ManagedExecutor and Mutiny controls, failure checks, and concurrent HTTP tests against the packaged JVM app. the-main-thread.com/p/quarku…

Quarkus MDC: Follow a Request ID Through Async Code

Trace a request ID through managed tasks and external callbacks, then test context propagation with overlapping requests.

Why your Kafka topic ignores retention.ms (and how to fix it) | Red Hat Developer

A customer opened a support case with a deceptively simple complaint: a Kafka topic was configured with a 12-hour retention (retention.ms), yet messages produced on July 24 were still readable 4 days

Zazr 0.3.0 is out 🎉 Zazr types now go in and out of JSON, with Jackson 3 or avaje-jsonb: • one dependency, same JSON with both • a `NonEmptyVector` can't arrive empty • no null slips into a collection zazr.dev/blog/json/

Zazr types in JSON, with Jackson and avaje-jsonb

Zazr 0.3.0 reads and writes Zazr types as JSON with Jackson or avaje-jsonb: one dependency, one JSON format, and the guarantees of the types kept at the boundary.
