Log File Request Counts Per Domain

MediumSQL · PostgreSQL

Problem

Given a log file containing request records for different domains, output the number of requests for each domain.

Use the canonical domain list and request log records provided. Include registered domains with zero requests, and exclude request records whose domain is not present in the canonical list.

Output

  1. One row per registered domain, with columns domain and request_count
  2. Sort by request_count descending, then domain ascending to break ties
