Abstract: The disclosed technology addresses the need in the art for a content management system that can be highly flexible to the needs of its subjects. The present technology permits any object to be shared by providing a robust and flexible access control list mechanism. The present technology utilizes a data structure that is highly efficient that both minimizes the amount of information that needs to be written into any database, but also allows for fast reads and writes of information from authoritative tables that are a source of truth for the content management system, while allowing for maintenance of indexes containing more refined data that allow for efficient retrieval of certain information that would normally need to be calculated when it is needed.

Abstract: The present technology pertains to a link service that can create, maintain, and service links to objects on behalf of a content management system or other services. The link service can share administration of links with other services when desired or can even allow other services to issue the link and manage the object that is the subject of the link while providing other functions to support the link. Additionally, link service can interface with a file system that can support links as actors in the file system, whereby greater control and flexibility in supporting links is provided. Link service can also accommodate servicing and management of links issued by legacy services, where the legacy services have unique link logic that should still be utilized to maintain a consistent user experience.

Abstract: A software and hardware facility persistently maintains metrics on directories at different levels within a tree of a filesystem. The facility hierarchically aggregates attributes of files contained by directories and stores them as metric values in each directory within a tree. The stored values represent summed or otherwise aggregated data from the descendant directories and files. The metric values represent aggregated attributes such as checksums, MIN and/or MAX aggregates, sameness bits, bloom filter aggregates, queryable user tags, moving average aggregates, b-tree aggregates, etc.

Abstract: A transactional block storage system is provided which is capable of supporting a single-phase commit for data writes specifying a protected storage unit. The storage system includes a data storage map that logically links the protected data storage unit to two or more block storage units associated with a layer of the protected data storage unit. The storage system also includes an address abstraction layer which translates write requests to the block storage units and resolves whether those write requests are atomically committed to the storage system in a single phase transaction. The address abstraction layer is further configured to detected when a block storage unit becomes unavailable during a transaction and create a cleaning kit for that block in order to prevent data loss. Additionally, the address abstraction layer facilitates moving, copying, and merging of block storage units without global locking in the storage system.
