Abstract
Techniques for maintaining immutable data and mutable metadata in a storage system are disclosed. Each object is associated with one or more data records and one or more metadata records. Responsive to a request to modify the data of an object, a new data record and a new metadata record are generated for the object. The new data record stores the new data of the object. The new metadata record stores the new metadata corresponding to the new data of the object. Responsive to a request to modify the metadata of an object, an existing metadata record of the object is identified. The existing metadata record is overwritten with the new metadata of the object. No new data records or metadata records are generated.
