obs — v2026.10.21

Query every partition at once rather than downloading them individually — hive_partitioning exposes the directory name as a column you can filter on:
SELECT * FROM read_parquet('https://storage.googleapis.com/calcofi-db/ducklake/releases/v2026.10.21/parquet/obs/**/*.parquet', hive_partitioning = true) LIMIT 10;
