SQL Top 10% Creators by Engagement

MediumSQL · PostgreSQL

Problem

Write a SQL query to identify the top 10% of creators based on engagement metrics over the last 30 days.

Use the provided creators and creator_engagements tables. Treat engagement as the sum of likes, comments, and shares. Include creators with no qualifying activity, and use the current date as the reference date.

Output

  1. One row per selected creator with creator_id, creator_handle, total_engagements, and creator_rank.
  2. Include exactly the top 10% of creators, rounded up, with deterministic ordering by engagement descending and creator ID ascending for ties.
  3. Sort by creator_rank ascending.
