Storage tasks is a serverless framework that simplifies the processing of millions of stored objects based on complex logical conditions you specify for Blobs and Data Lake Storage Gen2. Storage tasks enable you to perform common operations, such as changing tiers, deleting or undeleting objects, setting blob index tags, modifying POSIX ACLs, managing immutability settings and more. Storage tasks provides a no-code composition experience allowing you to compose once, apply to dozens of storage accounts and schedule to run in the background.
