Multi-Tenant Observability for Serverless Tracing
Design a distributed tracing and observability platform specifically for serverless environments (like AWS Lambda). The system must process 1 billion spans per day. Since serverless functions are ephemeral, traditional agents won't work. The system must support 'trace-stitching' across asynchronous boundaries (queues, pub/sub) and provide per-tenant billing based on data volume and query complexity.
