About keboola

The Keboola extension exposes Keboola Storage as a native DuckDB database. Once attached, you can use standard SQL to read from and write to Keboola tables, join Keboola data with local DuckDB tables, and manage schemas.

Features:

• SELECT with filter and projection pushdown to Keboola Query Service
• INSERT, UPDATE, DELETE via Keboola Storage Importer API
• CREATE TABLE, CREATE SCHEMA, DROP TABLE, DROP SCHEMA DDL support
• SNAPSHOT mode: pull all data locally for offline/low-latency queries
• Secret management for secure credential storage
• Native Keboola type mapping (Snowflake types → DuckDB types)
• Table and column descriptions from KBC metadata
