Snowflakes to Databricks Migration Guide - Nuvento

1. A MIGRATION STORY

2. WHY MIGRATE TO DATABRICKS? Migrating to Databricks offers a range of benefits that can help organizations achieve their goals faster and more efficiently. With improved performance and scalability, businesses can process and analyze large amounts of data quickly and easily. In addition, Databricks provides cost savings by reducing the need for expensive hardware and infrastructure. According to recent studies, companies that migrate to Databricks can see up to a 50% reduction in total cost of ownership compared to on- premises solutions. This is due to Databricks' cloud-based architecture, which eliminates the need for expensive hardware and maintenance costs. Additionally, Databricks provides a unified analytics platform that enables teams to work collaboratively and share insights across departments.

3. CHALLENGES WITH SNOWFLAKE One of the major challenges with Snowflake is its query performance. While Snowflake provides a scalable and elastic architecture, queries can sometimes take longer than expected due to the way data is stored and distributed across multiple nodes. This can lead to slower response times and increased costs as more compute resources are required to handle the workload. Another challenge with Snowflake is data silos. Snowflake's multi-cluster shared data architecture allows for different clusters to access the same data, but this can also create silos where different teams or departments have their own separate clusters and don't share data. This can result in duplication of efforts and inconsistent data across the organization.

4. DATABRICKS OVERVIEW Databricks is a unified data analytics platform that provides a collaborative workspace for teams to work together on big data projects. With Databricks, you can easily analyze and visualize large datasets, build machine learning models, and deploy production-ready applications. One of the key features of Databricks is its collaborative workspace, which allows multiple users to work together on the same project in real- time. This makes it easy to share code, notebooks, and data with your team, and collaborate on complex projects more efficiently. Databricks also has built-in support for popular programming languages like Python, R, and SQL, making it easy to integrate with your existing workflows.

5. MIGRATION STRATEGY Migrating from Snowflake to Databricks requires a well-planned strategy that takes into account data preparation, testing, and deployment. The first step is to identify the data sources and determine which ones need to be migrated. It's important to clean and transform the data before migrating it to Databricks, as this will ensure better performance and accuracy. Once the data has been prepared, it's time to test the migration process. This involves running queries and scripts on both Snowflake and Databricks to ensure that the results are consistent. It's also important to test the scalability and performance of the system under different workloads. Finally, the data can be deployed to Databricks using a variety of methods, such as batch processing or real-time streaming.

6. CONCLUSION In conclusion, migrating to Databricks offers a range of benefits that Snowflake simply cannot match. With improved performance, scalability, and cost savings, it's clear that Databricks is the superior choice for data analytics and machine learnin By overcoming the limitations and challenges of Snowflake, businesses can unlock their full potential with Databricks. From unified data analytics to collaborative workspaces and advanced machine learning capabilities, the possibilities are endless. www.nuvento.com
