+
+What is Apache Arrow?
+---------------------
+Apache Arrow is a columnar in-memory analytics layer designed to
+accelerate big data. It houses a set of canonical in-memory
+representations of flat and hierarchical data along with multiple
+language-bindings for structure manipulation. It also provides
+low-overhead streaming and batch messaging, zero-copy interprocess
+communication (IPC), and vectorized in-memory analytics
+libraries. Languages currently supported include C, C++, C#, Go, Java,
+JavaScript, Julia, MATLAB, Python, R, Ruby, and Rust.
+
+What is Apache Arrow ADBC?
+--------------------------
+ADBC is a database access abstraction for Arrow-based applications. It
+provides a cross-language API for working with databases while using
+Arrow data, providing an alternative to APIs like JDBC and ODBC for
+analytical applications. For more, see [4].
+
+Please report any feedback to the mailing lists ([5], [6]).
+
+Regards,
+The Apache Arrow Community
