ADBC (Arrow Database Connectivity) is an API standard for Arrow-based database access.
An Arrow-based interface between applications and database drivers. ADBC aims to provide a vendor-independent API for SQL and Substrait-based database access that is targeted at analytics/OLAP use cases.
This API is intended to be implemented directly by drivers and used directly by client applications. To assist portability between different vendors, a "driver manager" library is also provided, which implements this same API, but dynamically loads drivers internally and forwards calls appropriately.
