Interview Prompt
The CDN team is comparing API traffic at the edge locations that are actually caching: those that have logged at least one cache hit on any path. For request paths that include 'api', find the average bytes served at each of those edge locations and path combination, from the lowest average to the highest.
Summary
Some edges keep the cache warm. Measure what they carry.
