Other queries or transactions that are waiting to acquire the same lock are blocked except for AccessShareLock. The key feature of data catalogs is to provide metadata context to the user in a way that allows different teams within the organization (both IT and Non-IT) to discover and understand relevant data. It simplifies access and promotes collaboration allowing an organization to more intelligently use their data. Get all your data in one place in minutes.
