About databricks

The Databricks extension attaches one Unity Catalog catalog as a DuckDB database. Tables are read and written with ordinary DuckDB SQL through the SQL Statement Execution API. It does not read Delta files, and it does not open a Thrift session. Filters, projections, LIMIT, and ORDER BY ... LIMIT can be pushed down to the warehouse.

Features include:

• ATTACH support for a Databricks catalog, including secrets for a personal access token or a service principal
• reads from attached schemas and tables
• writes with INSERT, COPY, CREATE TABLE AS, UPDATE, DELETE, and TRUNCATE
• databricks_query and databricks_execute for Databricks SQL that DuckDB cannot express
