The modern data stack suffers from a fundamental fragmentation problem. Data teams today juggle multiple schema formats across their architecture: OpenAPI for REST APIs, Protobuf for gRPC services, Avro for streaming platforms, and SQL DDL for data warehouses. This schema proliferation creates data governance nightmares, introduces quality issues at every boundary, and forces engineering teams to maintain multiple sources of truth.
Bufstream and Databricks are partnering to solve these issues.
The Universal Schema Approach
With Buf a single schema definition in Protobuf can govern your entire data flow, from API contracts to streaming topics to analytical tables. This universal schema approach doesn't just reduce complexity; it transforms data governance by ensuring that data producers' domain knowledge and validation rules flow seamlessly to every downstream consumer.
Consider the typical data journey in today's lakehouse architectures. Raw data enters through APIs and streaming platforms, often semi-structured and loosely validated. Data engineers then spend significant time in bronze and silver layers of medallion architectures, cleaning and structuring this data before it becomes analytics-ready. But what if clean, well-structured data could land directly in your analytical tables from the start?
Bufstream now supports Databricks Managed Iceberg Tables (in private preview), bringing together Buf's schema-first approach with Databricks' industry-leading data governance and optimization capabilities.
Databrick’s Managed Iceberg Tables
Recently announced, Managed Iceberg Tables represent Databricks' most significant advancement in open lakehouse architecture to date. These tables will fundamentally change how organizations think about data lake table management by bringing the simplicity of managed database tables to the open, interoperable world of Apache Iceberg.
Managed Iceberg Tables integrate natively with Unity Catalog's fine-grained governance model, providing consistent security policies, data lineage, and access controls across both Databricks and external engines. This unified governance layer addresses one of the biggest challenges in multi-engine data architectures: maintaining consistent security and compliance policies across different compute platforms.
Bufstream + Databricks: Schema-Driven Data Excellence
The combination of Bufstream and Databricks Managed Iceberg Tables creates an unprecedented data pipeline that ensures data quality from source to analytics:
- Schema-First Data Ingestion: With Bufstream's semantic validation at ingest, your Protobuf schemas become enforceable contracts. Data that doesn't match your schema never enters your system, preventing downstream quality issues before they start.
- Real-Time Schema Evolution: As your schemas evolve, Bufstream's direct writes to Iceberg automatically handle table schema updates, ensuring your analytical tables stay in sync with your operational data models without manual intervention.
- End-to-End Data Lineage: Combine Bufstream's schema-based lineage with Unity Catalog's automated tracking to get complete visibility into how data flows from your APIs and Kafka topics all the way to your analytical queries.
- Operational Simplicity: Define your data contracts once in Protobuf. Bufstream handles the streaming ingestion and validation. Databricks manages the storage optimization. Your data teams can focus on generating insights instead of maintaining infrastructure.
Getting Started
This integration represents more than just technical compatibility—it's a fundamental shift toward treating schemas as the foundation of your entire data architecture. When your API schemas, streaming schemas, and table schemas are unified, data governance becomes automatic, data quality improves dramatically, and your teams can move faster with confidence.
