  title: Vineyard Python Client Blobs Metadata API
  description: The Vineyard Python client API provides programmatic access to the Vineyard in-memory immutable data manager (v6d), a CNCF project. Clients connect via IPC (UNIX domain socket) for zero-copy local access or via RPC (TCP) for remote access. The API supports storing, retrieving, naming, persisting, and deleting distributed in-memory objects.
