The original title is: "Ad-Hoc Video Analytics with DuckDB on Parquet Exports from Production SQLite"

Short summary

A developer demonstrates separating operational and analytical workloads by exporting production SQLite snapshots to Parquet and querying them locally with DuckDB. A nightly PHP script reduced analytical queries from 20+ minutes to 4 seconds while avoiding production database load. This pattern enables fast exploratory analytics on minimal infrastructure.

• •Export production SQLite data to hive-partitioned Parquet files nightly via DuckDB CLI
• •Query Parquet locally with DuckDB for sub-second analytical results
• •Separates analytical and operational workloads without infrastructure scaling
