The In-Process Revolution
Unlike traditional databases that require a separate server, DuckDB runs inside your application. This eliminates the network as a bottleneck and enables zero-copy data transfer for unparalleled efficiency.

The Trifecta of Performance
1. Columnar Storage
DuckDB reads only the columns you need, drastically reducing I/O compared to row-based systems. For analytics, this means less data read and faster results.
2. Vectorized Execution
Instead of processing row-by-row, DuckDB processes data in batches (vectors). This minimizes overhead and fully leverages modern CPU cache and SIMD capabilities.
3. Morsel-Driven Parallelism
DuckDB automatically parallelizes queries across all available CPU cores, scaling its performance nearly linearly for complex operations like aggregations and joins.
A Rich & Extensible Ecosystem
DuckDB is more than just a fast engine. It's a full-featured database with a modular design, allowing you to load extensions for cloud storage, new file formats, and direct connections to other databases.
