+## InfluxDB 3.0
+
+The [flightsql-dbapi](https://pypi.org/project/flightsql-dbapi/) provides a DB API 2 interface and SQLAlchemy Dialect for Flight SQL that interacts with [InfluxDB 3.0](https://www.influxdata.com/products/influxdb-overview/). The primary SQLAlchemy Dialect provided by flightsql-dbapi targets the DataFusion SQL execution engine.

+### DSN to connect InfluxDB 3.0 to Superset
