spice-connect-data

Connect Spice to data sources and query across them with federated SQL — including datasets, catalogs, views, and writes. Use this skill whenever the user wants to set up federated queries across multiple sources, create views, configure catalogs (Unity Catalog, Databricks, Iceberg), write data with INSERT INTO, or understand how Spice's query federation works. This skill focuses on the federation layer — cross-source joins, views, catalogs, and data writes. For configuring individual data source connectors (PostgreSQL params, S3 file formats, etc.), see spice-data-connector.
