deephaven.dbc.adbc

This module supports ingesting data from external databases (relational and other types) into Deephaven via the Python DB-API 2.0 (PEP 249) and the Apache Arrow Database Connectivity (ADBC) interfaces. (Please refer to https://arrow.apache.org/docs/dev/format/ADBC.html for more details on ADBC).

ADBC defines a standard API to fetch data in Arrow format from databases that support Arrow natively as well as from databases that only support ODBC/JDBC. By relying on ADBC, Deephaven is able to ingest data efficiently from a wide variety of data sources.
