Modern data governance

Healthcare Company Modernizes Data Governance with Databricks Unity Catalog

A leading healthcare revenue cycle management company faced the challenge of modernizing its data governance framework to enhance security, streamline data access, and improve operational efficiency. Their existing Hive Metastore catalog presented difficulties due to its decentralized structure and the need to manage diverse client-specific data repositories.

In response to these challenges, the company partnered with Wavicle to migrate to Databricks Unity Catalog, a modern data governance solution. Despite complexities such as client-specific requirements and ongoing pipeline updates, the migration was completed successfully in just two months. This transformation resulted in improved data security, simplified operations, and reduced maintenance efforts, enabling the organization to scale its data capabilities and better serve its clients.

Confronting the limitations of Hive Metastore  

The healthcare company’s reliance on Hive Metastore for data governance had become increasingly unsustainable as their operations scaled. While Hive had been a reliable solution in the past, it fell short of addressing the demands of a modern, secure, and efficient data ecosystem.

One significant challenge stemmed from Hive’s inability to provide centralized governance across the organization. Each client’s data repository had unique configurations, permissions, and attributes, resulting in fragmented data governance processes. This lack of uniformity made it increasingly difficult to manage access controls, enforce policies, and maintain operational efficiency.

Security and compliance presented another critical hurdle. Hive lacked fine-grained permission controls, a key requirement in meeting healthcare industry regulations like HIPAA. Additionally, the absence of lineage tracking made it nearly impossible to trace data transformations, creating blind spots in auditing and regulatory reporting. These gaps exposed the organization to potential compliance risks and reduced their confidence in the overall data governance framework.

Lastly, as the organization continued to update its data pipelines to improve performance and scalability, Hive struggled to keep pace. Synchronizing ongoing pipeline changes with legacy data governance processes introduced risks of data inconsistencies and disruptions in meeting service-level agreements (SLAs).

Faced with these mounting challenges, the company recognized the urgent need for a modern, centralized data governance solution. Migrating to Databricks Unity Catalog emerged as the ideal choice, offering robust capabilities such as centralized governance and fine-grained permissions. To execute this complex migration, they sought Wavicle’s expertise. With a proven track record in navigating intricate data migrations and implementing scalable, secure frameworks, Wavicle was the trusted partner to lead this transformation.

Building a unified and secure data environment with Databricks Unity Catalog 

To overcome the data governance and operational inefficiencies posed by the legacy Hive Metastore, the healthcare company partnered with Wavicle to design and execute a seamless migration to Databricks Unity Catalog. This transformation aimed to centralize governance, enhance security, and provide the scalability required for their data-driven operations, all while ensuring compliance with HIPAA regulations.

Wavicle began by conducting a thorough assessment of the company’s Hive Metastore catalog, which housed 80 schemas and 2TB of critical data. The team identified the complexities stemming from client-specific repositories, diverse metadata structures, and inconsistent access controls. Using this analysis, Wavicle designed a unified catalog structure tailored to accommodate the company’s unique client requirements while enabling centralized data governance.

A key objective of the migration was ensuring zero downtime during the transition. Recognizing the healthcare company’s reliance on uninterrupted data access to meet SLAs and provide timely insights, Wavicle implemented a parallel processing framework. This approach synchronized ongoing pipeline updates with the migration process, ensuring seamless data delivery and eliminating disruptions to daily operations.

To execute the migration efficiently, Wavicle utilized Databricks’ advanced Deep Clone functionality, creating precise snapshots of the legacy Hive data. Automation was a cornerstone of the process, with Wavicle leveraging Databricks APIs and custom Python scripts to automate the migration of schemas, tables, properties, and permissions. This not only accelerated the project timeline but also minimized the risk of manual errors. 

Throughout the migration, rigorous testing and validation were conducted to ensure data consistency, security, and compliance. The team implemented validation frameworks to compare pipeline outputs from Unity Catalog with legacy Hive data, confirming the accuracy and reliability of the new system. Fine-grained permissions provided by Unity Catalog enabled role-based access at every level, ensuring that all data governance policies aligned with standards like HIPAA.

Wavicle successfully delivered the migration within just two months, achieving a seamless transition without any downtime. By leveraging Databricks Unity Catalog, the healthcare company now benefits from a centralized and modernized data governance solution. This transformation will help the organization to better meet client needs, support future growth, and realize the full potential of their data ecosystem. 

Enabling the foundation for integrated management and governance of the data ecosystem  

Wavicle’s expertise ensured a smooth migration of 80 schemas and 2TB of data to Databricks Unity Catalog with zero downtime. By automating the process and implementing parallel processing, all pipeline updates were synchronized, ensuring continuous data availability and meeting SLAs without disruption.

The healthcare company now benefits from a centralized governance system, offering improved security, compliance with HIPAA standards, and streamlined data access. The automated updates to metadata and schemas reduced manual maintenance, while faster data delivery and reduced complexity set the stage for scalable growth.

With Wavicle’s tailored approach, the healthcare company not only modernized its data governance but also laid the foundation for long-term innovation and operational excellence. This conversion positions the organization as a leader in healthcare data management, ready to tackle future challenges and deliver superior value to its clients.
