+## Databricks
+
+To connect to Databricks, first install [databricks-dbapi](https://pypi.org/project/databricks-dbapi/) with the optional SQLAlchemy dependencies:
+
+```bash
+pip install databricks-dbapi[sqlalchemy]
+```
+
+There are two ways to connect to Databricks: using a Hive connector or an ODBC connector. Both ways work similarly, but only ODBC can be used to connect to [SQL endpoints](https://docs.databricks.com/sql/admin/sql-endpoints.html).
+
+### Hive
+
+To use the Hive connector you need the following information from your cluster:
+
+- Server hostname
+- Port
+- HTTP path
+
+These can be found under "Configuration" -> "Advanced Options" -> "JDBC/ODBC".
+
+You also need an access token from "Settings" -> "User Settings" -> "Access Tokens".
+
+Once you have all this information, add a database of type "Databricks (Hive)" in Superset, and use the following SQLAlchemy URI:
+
+```
+databricks+pyhive://token:{access token}@{server hostname}:{port}/{database name}
+```
+
+You also need to add the following configuration to "Other" -> "Engine Parameters", with your HTTP path:
+
+```
+{"connect_args": {"http_path": "sql/protocolv1/o/****"}}
+```
+
+### ODBC
+
+For ODBC you first need to install the [ODBC drivers for your platform](https://databricks.com/spark/odbc-drivers-download).
+
+For a regular connection use this as the SQLAlchemy URI:
+
+```
+databricks+pyodbc://token:{access token}@{server hostname}:{port}/{database name}
+```
+
+And for the connection arguments:
+
+```
+{"connect_args": {"http_path": "sql/protocolv1/o/****", "driver_path": "/path/to/odbc/driver"}}
+```
+
+The driver path should be:
+
+- `/Library/simba/spark/lib/libsparkodbc_sbu.dylib` (Mac OS)
+- `/opt/simba/spark/lib/64/libsparkodbc_sb64.so` (Linux)
+
+For a connection to a SQL endpoint you need to use the HTTP path from the endpoint:
+
+```
+{"connect_args": {"http_path": "/sql/1.0/endpoints/****", "driver_path": "/path/to/odbc/driver"}}
+```
