Problem

We collect structured logs from a fleet of machines. Each machine runs many processes, and we need to track when each process runs and how long it takes. Data scientists need to query metrics like average elapsed time per process and plot process timelines across machines. Design the data model, and describe how you'd load this data via an ETL.
