Conclusion
In this article, you learned how to set up Redash Databricks Integration. It also gave an overview of Redash and Databricks with their key features. You also learned about the benefits of setting up this integration. You can now create your Redash Databricks Integration to leverage the benefit of both these platforms in one place.
Integrating Redash with Databricks is a fantastic option if you have large volumes of data on Redash waiting to break out of silos and provide valuable insights.
However, Databricks doesn’t provide native connections (like Redash) with other data sources or databases like MySQL, PostgreSQL, MongoDB, etc, and you’ll spend a lot of time migrating data from these sources to Databricks. This is where Hevo comes in.
Replicating the data from various sources into Databricks by writing custom scripts can prove to be a tedious process and will create a slug of errors and data consistency issues.
However, connecting to Databricks using a Data Integration tool like Hevo can perform this process with no effort and no time. Hevo’s No-code Data Pipeline allows you to automatically transform and move data from multiple sources into Databricks for further analysis.
