Push-Based CDC into Unity Catalog with Zerobus Ingest and Debezium
Databricks, Thursday, November 5th, 2026
A new open-source Debezium Server sink pushes CDC events directly into Unity Catalog Delta tables via Databricks Zerobus Ingest, without Kafka.
Databricks and NVIDIA built and contributed a Zerobus Ingest sink to the open-source Debezium project, shipped in Debezium Server 3.7.
It lets teams that own databases in restricted networks push change data capture events from logs such as the PostgreSQL write-ahead log directly into Unity Catalog Delta tables.
This replaces a two-hop architecture through a Kafka cluster, removing the need to plan brokers and partitions and run separate ingestion jobs.
Databricks built the typed sink, while NVIDIA contributed envelope mode, which lands full Debezium change events with safeguards such as idempotency keys and durable acknowledgment before source offsets advance.
