Arrow Flight SQL is a protocol for interacting with SQL databases using the Arrow in-memory format.

It is column-oriented, compact, and extremely performant compared to legacy protocols such as JDBC and ODBC.

FlightSQL endpoint is typically exposed as:

datafusion+flightsql://kamu:kamu@<api-server hostname>:50050?insecure=True

Please refer to Integrations page for some examples of FlightSQL protocol use.
