Reducing origin egress without caching: Request collapsing magic

Managing costs and performance while maintaining reliable services is a constant challenge for platform engineers. One significant pain point is origin egress: cloud provider fees that increase as user requests, such as API calls or live data streams, flood backend systems. Request collapsing offers a solution. This technique deduplicates traffic at the edge, reducing the need for storage while improving efficiency. By merging multiple identical requests into one at the edge, it reduces egress by up to 99% and stabilizes latency. Beyond cost reduction, request collapsing improves resilience by alleviating strain on origin systems during traffic spikes, such as viral content or seasonal surges. In this talk, attendees will learn how to apply request collapsing to their platforms, reducing both operational costs and complexity without relying on caching. This proven approach can lead to more efficient, resilient, and cost-effective developer workflows.
