Duckdb
ericrisco/rsc-harnessUse when analytical SQL must run in-process with no server: Parquet/CSV/JSON/Arrow queried in place, OLAP embedded in an app or notebook, a slow pandas groupby on multi-GB data, or S3/lakehouse data read without downloading. NOT a multi-user analytics server (that is clickhouse-analytics), NOT an app's transactional CRUD store (that is postgresdb).
At a glance
This skill is for Data & Analytics and helps you query parquet files with sql, analyze multi-gb datasets in notebooks, and perform olap queries without a server.
