From Delta Sharing to OpenSharing: what changed, what's next

In June 2026 Databricks and the Linux Foundation announced that Delta Sharing has evolved into OpenSharing, an open, vendor-neutral protocol under the Linux Foundation AI & Data Foundation that extends sharing beyond tables to volumes, agent skills, and AI models, and adds Apache Iceberg REST Catalog support and on-premises or private cloud reach. Existing Delta Sharing clients and integrations remain compatible, and enabling OpenSharing on a Unity Catalog metastore is a configuration step rather than a migration. Databricks also introduced capabilities on top of the protocol, including SecureConnect (generally available), Global Distribution (private preview), Genie Agent Sharing (beta), and Lakebase table and change data feed sharing (public preview).
