We conclude the series by dissecting the ‘Catch-and-Commit’ anti-pattern and establishing why a Dead Letter Queue is an architectural mandate, not a luxury.https://tuanhiep.github.io/principal/posts/series_3/3.the_protocol_trap_broker_semantics/Sun, 19 Apr 2026 00:00:00 +0000https://tuanhiep.github.io/principal/posts/series_3/3.the_protocol_trap_broker_semantics/Distributed brokers use leases to detect life. We dissect how the ‘MAX_VALUE’ configuration trap disables a system’s autonomic immune response, turning transient failures into permanent paralysis.https://tuanhiep.github.io/principal/posts/series_3/2.concurrency_collapse_thread_starvation/Sat, 18 Apr 2026 00:00:00 +0000https://tuanhiep.github.io/principal/posts/series_3/2.concurrency_collapse_thread_starvation/Asynchronous frameworks do not eliminate latency; they merely shift the bottleneck. We dissect how a single blocking I/O call inside a reactive pipeline can trigger a catastrophic thread starvation event.https://tuanhiep.github.io/principal/posts/series_3/1.the_observability_mirage_zombie_consumers/Fri, 17 Apr 2026 00:00:00 +0000https://tuanhiep.github.io/principal/posts/series_3/1.the_observability_mirage_zombie_consumers/When a dashboard reports 100% health but throughput is zero, the system isn’t dead—it’s paralyzed. We dissect thread starvation, the illusion of structural health checks, and the math behind a system collapse.
