Source Connector for Databricks - without Unity Catalog¶

This guide describes how to configure digna to connect to Databricks using either the native Python connector or the ODBC driver.

It refers to the screen "Create a Database Connection".

Create a database connection

Native Python Driver¶

Library: databricks-sql-connector
Supported Authentication: Personal Access Token (PAT) only

⚠️ For other authentication methods, please use the ODBC driver.

Personal Access Token (PAT)¶

To authenticate using a personal access token, refer to the official Databricks documentation:
👉 How to obtain a PAT

digna Configuration (Native Driver)¶

Provide the following information in the "Create a Database Connection" screen:

Technology:      Databricks (Legacy)
Host Address:    Databricks hostname, e.g. "xxxxxxxxxxxxxxxxxxx.databricks.com"
Host Port:       443
Database Name:   This parameter is not in use for databricks without unity catalog
Schema Name:     Schema that contains the source data
User Name:       HTTP Path provided by Databricks, e.g. "/sql/1.0/warehouses/xxxxxxxxxxxxxxx"
User Password:   Personal Access Token, e.g. "dapixxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
Use ODBC:        Disabled (default)

ODBC Driver¶

The ODBC driver supports a broader range of authentication and connectivity options. This section focuses on token-based authentication using the Simba Spark ODBC Driver.

1. Install the ODBC Driver¶

Install the Simba Spark ODBC Driver by following the vendor’s official installation guide.

2. Configure the ODBC Data Source¶

Follow these steps to configure a new ODBC data source using a Personal Access Token:

Step 1¶

Step 1

Step 2¶

Step 2

Step 3¶

Step 3

Step 4¶

Step 4

Step 5 – Test the connection¶

Click the TEST button. A successful connection should look like this:

Step 5

Now you can configure digna to use the ODBC connection, either with a DSN (Data Source Name) or a DSN-less setup.

A. DSN-Based Configuration¶

digna Configuration¶

In the "Create a Database Connection" screen, provide the following:

Technology:      Databricks (Legacy)
Database Name:   This parameter is not in use for databricks without unity catalog
Schema Name:     Schema that contains the source data
Use ODBC:        Enabled

ODBC Properties¶

name: "DSN",    value: "*digna*data_databricks"

🔹 The DSN must match the name defined in your ODBC driver configuration.

B. DSN-less Configuration¶

digna Configuration¶

In the "Create a Database Connection" screen, provide the following:

Technology:      Databricks (Legacy)
Database Name:   This parameter is not in use for databricks without unity catalog
Schema Name:     Schema that contains the source data
Use ODBC:        Enabled

ODBC Properties¶

name = "Driver",          value = "{Simba Spark ODBC Driver}"
name = "Host",            value = "xxxxxxxxxxxxxxxxxxx.databricks.com"
name = "Port",            value = "443"
name = "HTTPPath",        value = "/sql/1.0/warehouses/xxxxxxxxxxxxxxx"
name = "SSL",             value = "1"
name = "ThriftTransport", value = "2"
name = "AuthMech",        value = "3"
name = "UID",             value = "token"
name = "PWD",             value = "dapixxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
