Objects (content-addressed)

One immutable object per table or partition under ducklake/tables/, shared by every release whose catalog points at it. since is the first release that shipped this exact content; new marks what changed in v2026.08.25. Resolve tables through catalog.json objects[].path (e.g. calcofi4r::cc_release_sources(), calcofi4py.release_sources()) rather than the parquet/ path, which is kept only for the promoted and consolidated versions.

Why obs appears twice. Each is published both as a Hive-partitioned directory and as a single .parquet file, on purpose — they are the same rows.

The partitioned form lets DuckDB, R and Python skip whole partitions when you filter on the partition column, so it is the faster choice for most analysis. The single-file form exists because plain HTTPS has no directory listing: browser DuckDB-WASM (which powers calcofi.io/db-query) and other HTTPS-only consumers cannot expand a /**/*.parquet glob against cloud storage, so they need one addressable object. Removing either breaks a real consumer.
Read directly with DuckDB — no download needed. A single-file table:
SELECT * FROM read_parquet('https://storage.googleapis.com/calcofi-db/ducklake/releases/v2026.08.25/parquet/sample.parquet') LIMIT 10;

A partitioned table (note the /**/*.parquet glob and hive_partitioning, which turns the directory names into a real column):
SELECT * FROM read_parquet('https://storage.googleapis.com/calcofi-db/ducklake/releases/v2026.08.25/parquet/obs_ctd_full/**/*.parquet', hive_partitioning = true) LIMIT 10;
