Apache Arrow ADBC¶

ADBC: Arrow Database Connectivity

Cross-language, Arrow-native database access.

ADBC is a standardized set of APIs and libraries for fast, Arrow-native database access. Execute SQL queries, fetch results, ingest bulk data, explore catalogs, and more. ADBC uses Arrow columnar format to eliminate copies and conversions, speeding up data retrieval for analytics and AI applications.

Getting Started¶

Available Drivers

Connect to a growing list of databases using ADBC drivers.

Drivers
