Problem

We ingest about 2TB of raw application logs daily. Right now they're just text files in S3. We need a structured schema so analysts can query error patterns, correlate events within sessions, and track error rates by service. Can you design the data model?

Summary

Raw text files, terabytes of them, full of buried signals and cryptic error codes.
