Top Payout Creators by Region

HardSQL · PostgreSQL

Problem

Given a table of transactions and a table of creator profiles, write a query to find the top 5% of creators by total payout in each geographic region on Patreon.

Include creators with no transactions as having a total payout of zero, exclude profiles without a geographic region, and use a deterministic creator ID tie-breaker. Treat the top 5% as at least one creator per region, using the ceiling of 5% of the regional creator count.

Output

  1. One row per selected creator, with geographic_region, creator_id, creator_name, total_payout, payout_rank, and creator_count.
  2. Include only the selected top 5% of creators in each non-null region.
  3. Order by geographic_region, payout_rank, then creator_id.
