  title: Dapr Distributed Lock API
  description: >-
    The Dapr Distributed Lock API enables applications to acquire and release
    locks on shared resources, ensuring mutual exclusion across multiple
    application instances. Locks use a lease-based mechanism and are
    automatically released after expiry if not explicitly unlocked.
