Load Metadata from Databricks

Use the Databricks Loader to upload metadata to Alteryx Connect from a specified Databricks server.

Review Loader Requirements

The Alteryx Connect Loaders must be installed on the machine where Alteryx Server is installed. To install the loaders:

  1. Download the loaders installer. For compatibility, the Loaders installer version must match the Alteryx Connect version.

  2. Run the installer as an administrator.

Databricks must be accessible via ODBC:

  1. Download and install the Apache Spark on Databricks ODBC driver from the Alteryx Driver Download page.

  2. Configure and test a new DSN in the Windows ODBC Data Sources Administrator. For more information, see Create an ODBC Database Connection within the Alteryx Designer Help.Connexions aux bases de données ODBC et OLEDB

    If you are unsure about the correct host name and credentials, contact your IT administrator or check the connection details on Databricks under Compute > Select cluster > Configuration > Advanced options > JDBC > ODBC. For more information, visit the Databricks ODBC and JDBC drivers page.

Open the Loader

  1. Open Alteryx Designer.

  2. Select Help > Sample Workflows > Alteryx Connect Metadata Loaders > Databricks Loader > Databricks Loader.

  2. In the Databricks server tab:

    • Type the Databricks connection information, including ODBC Connection string (ODBC DSN connection name, e.g., DSN=myDatabricksDSN), Databricks Username, and Databricks Password.

    • For the ODBC Connection string, you can use:

      • Pre-configured ODBC DSN (system or user), such as DSN=Databricks.

      • Full connection string including driver name, host, port, and other additional parameters for the connection. For example: odbc:Driver=Simba Spark ODBC Driver;Host=inserthosthere;Port=443;SSL=1;Schema=default;HTTPPath=sql/protocolv1/o/0/0914-154522-ruled1;AuthMech=3;ThriftTransport=2;UseUnicodeSqlCharacterTypes=1;DefaultStringColumnLength=16777216;UID=token;

  4. Before running the app, select Save button and save the app configuration to the following directory:

    C:\ProgramData\Alteryx\AlteryxConnect\Databricks_Loader\
