DuckDB Performance

DuckDB achieves high performance through several mechanisms:

Columnar execution: Processes data in chunks of columns (vectors) rather than row-by-row.
Parallel execution: Automatically utilizes multiple CPU cores for queries.
Pushdown: When querying Parquet files, DuckDB pushes filters (WHERE clauses) down to the file reader, skipping irrelevant data blocks.

In our platform, DuckDB ensures dashboard queries complete in milliseconds.
