The other pages answer questions I chose. This page lets you ask your own.

DuckDB runs inside your browser, compiled to WebAssembly. It reads the same Parquet files the other pages read. Your query never reaches a server, and it cannot change the published data.

This page carries every published table. The catalog below shows its own SQL, as every page here does.

This page carries every published table, though this view hides the catalog query behind it. The box below still runs whatever you type.

The catalog

Start here. The query below lists every column of every table the site ships, with the type DuckDB reads it as.

SELECT table_name,
       column_name,
       data_type
FROM duckdb_columns()
WHERE NOT internal
ORDER BY table_name, column_index

The query box

Type SQL, then press Run. If a query fails, the page shows the error in place of the result and keeps working.

Three tables reward a first look. fact_run holds one row per run, spans holds one row per frame-time sample, and quarantine holds every record the contract rejected, with the reason.
