Embodiments are directed to a file system that include object stores. An object store for write requests may be provided. Write ahead log (WAL) entries that include data blocks may be generated. A WAL object may be generated based on the WAL entries and stored in the object store. An in-memory overlay may be updated to associate the data blocks with the WAL object. A checkpoint operation may be executed to: generate an index object that includes index entries that associate other data blocks with data objects stored in the object store; update the index object to include index entries that associate the data blocks with the WAL object; store the updated index object in the object store; update the in-memory overlay to remove the association of the data blocks and the WAL object and update the in memory WAL to remove records of successfully checkpointed WAL objects.

Object-based storage with garbage collection and data consolidation

Embodiments are directed to managing data in a file system. In response to a request from a client of a spoke file system to access file system items shared by a hub file system: determining a portion of the spoke file systems that may have an existing lock on the file system items; obtaining log entries from the portion of the spoke file systems such that the log entries are associated with commands that were executed in the portion of the spoke file systems; executing the commands in the hub file system to update the file system items in the hub file system; granting a lock on the file system items in the hub file system that enables the client to access the updated file system items from the spoke file systems.

Global namespaces for distributed file systems

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.

Aggregates index

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.

Data model and data service for content management system

Embodiments are directed to tiered data store with persistent layers. A write tier in the file system for storing in a file system. A value for a performance metric that corresponds to write requests to the file system may be predicted based on characteristics of the write requests such that the performance metric may be determined based on a plurality of interactions with the write tier. The predicted value that exceeds a threshold value of the performance metric may be employed to cause performance of further actions, including: queuing a portion of the write requests in a memory buffer based on the predicted value and the threshold value; combining the queued portion of the write requests into s; storing the data segments in the write tier such that a measured value of the performance metric may be less than the threshold value.
