Other releases and news

Introducing Jo and Shawn

We chat with Jo and Shawn about their background in the big data and data lake community and beyond.

Collate

We talk about the OpenMetadata open source project as a unified platform for data discovery, observability, and governance, with 80+ data connectors and a collaborative interface.

Jo and Shawn teach us about how OpenMetadata can help build and manage high quality data assets at scale, with case studies, documentation, and community resources and we dive into how Collate offers a platform around OpenMetadata and more.

Triple platform treat

Building a modern data platform isn’t just about picking tools—it’s about creating a unified ecosystem where performance, governance, and trust work seamlessly together. See how the power trio of Trino, Collate, and Apache Ranger transforms your data operations:

  • Trino: Lightning-fast analytics at scale. Query across any data source, any format, anywhere—without the complexity of data movement or vendor lock-in.
  • Collate: Intelligent data trust and discovery AI-powered profiling, automated quality testing, and smart alerting that keeps your data reliable and discoverable.
  • Apache Ranger: Enterprise-grade security and governance, fine-grained access controls, policy management, and audit trails that keep your data secure and compliant.

The integration advantage: Watch these three platforms work together to deliver what every data team needs—fast queries, trusted data, and bulletproof security—all in one cohesive stack.

Jo and Shawn tell us more about “Trino + Collate + Apache Ranger = Data Platform Excellence”, talk about the components and value provided by each of them, and dive in with a demo, while Manfred and Cole ask more questions to dive deeper.
