THE CLOUD EXPEDITION! · Chapter 7
Everything, Everywhere, All at Once
Every character gathers at the edge of Pondville — Shellbert, Cloudsworth, Marina, Aria, Chronos, and Dr. Velocity. Captain Cloudsworth wipes a tear: Five paradigms. One query. This is your MAGNUM OPUS, Duckbert. The crowd holds its breath. The ultimate test of All Five Paradigms — local, cloud, shared, external files, and time travel in a single query.
Your task
Unite all five paradigms in one query. Find the most well-traveled Pondville ducks, enriched with ecosystem quality, storm impact, and archived census data. Return <b>name</b>, <b>home_pond</b>, <b>ponds_explored</b> (distinct destinations), <b>avg_water_quality</b> (from ecosystem readings at destinations), <b>total_storm_pop_change</b> (total population shift across all districts from the storm), and <b>archived_total_pop</b> (total population from the Parquet census archive). Most-explored ducks first, 10 rows. Tables: `pondville_residents` (local), `dbquacks_cloud_expedition.duck_travels` (cloud, linked by `duck_id`), `dbquacks_marina_lake.ecosystem_readings` (shared, `pond_name` matches `destination_pond`), `dbquacks_living_lake.pond_census` (Ducklake, version 1 = pre-storm), and `read_parquet('https://data.dbquacks.com/archives/census_2025.parquet')` for the census archive.<br><br><b>Re-attach if needed:</b><ul><li><code>dbquacks_marina_lake</code> → <code>md:_share/marina_lake_db/3be07852-dfce-4b29-b415-99c9f7fdcc6a</code></li></ul>
