About
Columnar was founded by core Apache Arrow contributors to redefine data connectivity for the AI era, replacing 1990s-era row-oriented standards such as ODBC and JDBC with Arrow-native ADBC (Arrow Database Connectivity) drivers. By eliminating costly row/column format conversions between columnar databases and applications, the company claims 10x to 100x faster query retrieval on platforms like Snowflake and DuckDB. It also ships dbc, an open-source CLI for installing and managing ADBC drivers, and builds a commercial business around the Arrow/ADBC open-source ecosystem.
