Article: Using AWS Lambda Extensions to Run Post-Response Telemetry Flush

Melvin Philips — Wed, 15 Apr 2026 09:00:00 GMT

At Lead Bank, synchronous telemetry flushing caused intermittent exporter stalls to become user-facing 504 gateway timeouts. By leveraging AWS Lambda's Extensions API and goroutine chaining in Go, flush work is moved off the response path, returning responses immediately while preserving full observability without telemetry loss.

Article: Building Hierarchical Agentic RAG Systems: Multi-Modal Reasoning with Autonomous Error Recovery

Abhijit Ubale — Thu, 09 Apr 2026 09:00:00 GMT

In this article, the author explores how hierarchical agentic RAG systems coordinate specialized workers through structured orchestration to improve accuracy, reliability, and explainability in complex enterprise analytics workflows. The article uses Protocol-H as a to show how deterministic routing, reflective retry, and modality-aware reasoning support safer multi-source query execution.

Article: Stateful Continuation for AI Agents: Why Transport Layers Now Matter

Anirudh Mendiratta — Wed, 08 Apr 2026 09:00:00 GMT

Agent workflows make transport a first-order concern. Multi-turn, tool-heavy loops amplify overhead that is negligible in single-turn LLM use. Stateful continuation cuts overhead dramatically. Caching context server-side can reduce client-sent data by 80%+ and improve execution time by 15–29% .
