Unity Catalog beforehand supported Delta and Iceberg, along with Apache Hudi, one other open desk format, through Databricks’ Delta Lake UniForm format. In reality, Unity Catalog additionally helps Iceberg’s REST-based API, Ghodsi identified.
“We principally standardized the information layer and the safety layer so that you simply personal your knowledge and every thing goes by way of these open interfaces,” he mentioned. “And I feel that’s going to be superior for the neighborhood, for everyone in right here. As a result of we simply have far more use instances. We’re going to have the ability to do rather more innovation, and we’ll simply increase this marketplace for all people concerned.”
