Databricks Account using JDBC (Source: Any SQL Database)
In this article
Overview
You can use this account type to connect Databricks Snaps with data sources that use the Databricks account with JDBC as the source.
Prerequisites
A valid Databricks account.
Certified JDBC JAR File:Â databricks-jdbc-2.6.25-1.jar
Limitation
With the basic authentication type for Databricks Lakehouse Platform (DLP) reaching its end of life on July 10, 2024, SnapLogic Databricks pipelines designed to use this authentication type to connect to DLP instances would cease to succeed. We recommend that you reconfigure the corresponding Snap accounts to use the Personal access tokens (PAT) authentication type.
Known Issues
None.
