Cash in Your Change: Convert Mutations to AI Insights
summary
Claim: every GraphQL mutation becomes an immutable, auditable event feed that powers analytics and AI. Implementation captures all mutations at the Apollo Router via a native Apollo Router Rust plugin, streams JSON events into Current DB fine-grain streams (durable, ordered, replayable), and runs LLMs over a loan-application stream to return a JSON summary which is itself stored as an event. PII options include encryption, separate streams or crypto‑shredding; repo is open source and the alpha plugin demonstrably works.
