Efficient metadata storage

摘要: One or more techniques and/or systems are disclosed for efficiently storing metadata of partitioned data (e.g., directed to a specific individual/user). A first subset is identified from the set data. The comprises that has high frequency access, and may be identified, at least in part, by access associated with set. Metadata, such as discovery information, permissions, version info, etc., can stored low latency fast) storage, proving efficient access. Metadata not accessed frequently) higher slower, less expensive) storage.
