This also implements the ADBC APIs, but dynamically loads drivers and dispatches calls to them.\n\nLike JDBC/ODBC, the goal is to provide a generic API for multiple databases. ADBC, however, is focused on bulk columnar data retrieval and ingestion through an Arrow-based API rather than attempting to replace JDBC/ODBC in all use cases.\nHence, ADBC is complementary to those existing standards.\n\nLike [Arrow Flight SQL][flight-sql], ADBC is an Arrow-based way to work with databases.\nHowever, Flight SQL is a _protocol_ defining a wire format and network transport as opposed to an _API specification_. Flight SQL requires a database to specifically implement support for it, while ADBC is a client API specification for wrapping existing database protocols which could be Arrow-native or not.\nTogether, ADBC and Flight SQL offer a fully Arrow-native solution for clients and database vendors.\n\nFor more about ADBC, see the [introductory blog post][arrow-blog].\n\n[arrow-blog]: https://arrow.apache.org/blog/2023/01/05/introducing-arrow-adbc/\n[flight-sql]: https://arrow.apache.org/docs/format/FlightSql.html\n\n## Status\n\nADBC versions the API standard and the implementing libraries separately.\n\nThe API standard (version 1.0.0) is considered stable, but enhancements may be made.\n\nLibraries are under development.\nFor more details, see the [documentation](https://arrow.apache.org/adbc/main/driver/status.html), or read the [changelog](CHANGELOG.md).\n\n## Installation\n\nPlease see the [documentation](https://arrow.apache.org/adbc/main/driver/installation.html).\n\n## Documentation\n\nThe core API definitions can be read in `adbc.h`.\nUser documentation can be found at https://arrow.apache.org/adbc\n\n## Development and Contributing\n\nFor detailed instructions on how to build the various ADBC libraries, see [CONTRIBUTING.md](CONTRIBUTING.md).\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fapache%2Farrow-adbc","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fapache%2Farrow-adbc","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fapache%2Farrow-adbc/lists"}
