Simplicity of a Database, but the Speed of a Cache: OLAP Caches for DuckDB
DuckDB extensions like QuackStore, cache_httpfs, and DiskCache enable fast query caching without additional infrastructure. These tools cache remote files locally, reducing query times from minutes to seconds for BI dashboards and analytics workloads. The article demonstrates how to implement block-based caching, disk-backed storage, and immutable data lake patterns using DuckDB's embedded architecture, offering a simpler alternative to traditional OLAP cubes and materialized views.
