Semantic Layer Sync has been introduced to bridge the gap between the semantic layer and BI tools, enabling instantaneous self-serve analytics. The feature has expanded its support to include Tableau, allowing users to author data models in Cube Cloud and seamlessly synchronize them with Tableau Cloud or Desktop. This integration is now available on Premium tiers of Cube Cloud and can be accessed by checking the documentation. The update aims to save time for data engineers and enable self-serve analytics for end-users in BI tools.
