Moving from Polling to Push: WebSub Architectural Tradeoffs and Fallback Strategies
Rethinking Syndication Ingestion for High-Volume Feeds Traditional feed ingestion is usually built around a scheduler, a fetch queue, and a parser. That model is straightforward, but its cost grows quickly. If a platform monitors hundreds of thousands of RSS or Atom feeds, even a modest polling interval creates a large volume of requests that return […]
DOM vs. SAX: Controlling Memory Spikes During Massive Feed Parsing
The Hidden Threat of High-Volume Feed Ingestion Containerized ingestion workers often fail at the point where normal load turns into a payload burst. A service configured with 256 MB or 512 MB of memory may process ordinary RSS and Atom requests without difficulty, then be terminated as soon as a publisher sends an unusually large […]
How to Parse Custom XML Namespaces Without Breaking Feed Ingestion
Why Unpredictable XML Namespaces Crash Production Pipelines Real-world RSS, Atom, and syndication feeds rarely behave like a clean fixture in a parser test suite. Publishers add Dublin Core metadata, Media RSS elements, proprietary extensions, and vendor-specific attributes over time. They may change a prefix without changing its namespace URI, introduce a default namespace where none […]
