In accordance with exemplary embodiments of the present invention, a content addressable data structure system may include directed acyclic graphs (DAGs) of data content that are addressed using both a user-defined search key and content of data blocks. Internal keys of retention roots of the DAGs may be derived from the user-defined search key while the remaining blocks may be content addressed. As opposed to using a content address, the user may provide the search key when retrieving and deleting DAGs retaining the data content. In addition, the internal keys may be implemented using internal content addressable storage operations, such as applying a hash function and employing a distributed hash table. |
