Methods and systems for implementing a conflict resolution process in real-time editing of an online document by multiple users are provided. By adopting a multi-user conflict ID, the system can determine whether an editing conflict exists between two users' modifications of the same document. It can further generate a corresponding conflict resolution action based on a resolution model and synchronize multi-user modifications via serialization data. By enabling multiple users to collaboratively edit one document, e.g., an email, the present methods and systems can effectively optimize the workflow and efficiency of a team.

Aspects of the disclosure provide a data processing apparatus having interface circuitry and processing circuitry. The interface circuitry is configured to obtain data related to at least two resource accounts, and related to resource transfer of the at least two resource account. The processing circuitry configured to construct resource transfer relationships of the at least two resource accounts according to the data, calculate, based on the resource transfer relationships, similarity measurements between the at least two resource accounts according to a preset calculation rule, and output, according to the calculated similarity measurements, a resource account with a similarity measurement satisfying a preset condition.

A storage cluster includes a group of data nodes having concurrent access to a shared filesystem. The shared filesystem is assigned to a first TLU of a first storage group. Other filesystems of the data nodes associated with the shared filesystem, such as snapshot copies of the shared filesystems and the root/configuration filesystems of the data nodes are assigned to TLUs of a second set of storage groups. The first storage group and the second set of storage groups are all associated with a Remote Data Replication (RDR) group for the storage cluster. An RDR facility is created between a storage array storing the shared filesystem and a backup storage array. The concurrently accessed shared filesystem and the filesystems of all data nodes accessing shared filesystem are replicated on the RDR facility to the backup storage array to enable failover of the storage cluster between sites.

The disclosed technology relates to a system configured to detect a modification to a node in a tree data structure. The node is associated with a content item managed by a content management service as well as a filename. The system may append the filename and a separator to a filename array, determine a location of the filename in the filename array, and store the location of the filename in the node.

A method for data storage includes assigning multiple different portions of a given object, which is stored in non-volatile storage, for access by multiple respective software modules running on one or more processors. Storage operations are performed by the software modules in the portions of the given object. Respective local values, which are indicative of most recent times the storage operations were performed in the given object by the respective software modules, are updated by the software modules. A global value is updated for the given object, by consolidating updates of the local values performed by the software modules.

Throughput is preserved in a distributed system while maintaining concurrency by pushing a commit wait period to client commit paths and to future readers. As opposed to servers performing commit waits, the servers assign timestamps, which are used to ensure that causality is preserved. When a server executes a transaction that writes data to a distributed database, the server acquires a user-level lock, and assigns the transaction a timestamp equal to a current time plus an interval corresponding to bounds of uncertainty of clocks in the distributed system. After assigning the timestamp, the server releases the user-level lock. Any client devices, before performing a read of the written data, must wait until the assigned timestamp is in the past.

Non-limiting examples of systems, methods, and devices for programmatic modifications to files are disclosed herein. In an implementation, content of a file is auto-updated based on an association with an external resource. The external resource may access a data source and monitor for real-time status updates. When a status update is observed, the external resource captures the change and updates a version of the content based on the captured change. If necessary, the external resource may capture the change in a first format and transform the captured change into a second format that is compatible with the version of the content. State information of the updated version is then sent to the file and the content of the file may be updated according to the state information.

Provided are a computer program product, system, and method for switching serialization techniques for handling concurrent write requests to a shared file. A first node serializes write requests from client nodes to write to the shared file. The first node determines whether to switch to a second node to manage write quests to the shared file based on a pattern of write requests to the shared file. The client nodes are notified to direct write requests to the shared file to the second node in response to determining to switch to the second node. The second node processes write requests to the shared file to serialize writes to the shared file after the client nodes are notified to submit the write requests to the shared file to the second node.

The present technology pertains to a organization directory hosted by a synchronized content management system. The corporate directory can provide access to user accounts for all members of the organization to all content items in the organization directory on the respective file systems of the members' client devices. Members can reach any content item at the same path as other members relative to the organization directory root on their respective client device. In some embodiments novel access permissions are granted to maintain path consistency.

In some embodiments, a system for synchronizing content with client devices receives a request from a client device to synchronize operations pertaining to content items associated with a user account registered at the system. The request can include the operations and a cursor identifying a current position of the client in a journal of revisions on the system. Based on the operations, the system generates linearized operations associated with the content items. The linearized operations can include a respective operation derived for each of the content items from one or more of the operations. The system converts each respective operation in the linearized operations to a respective revision for the journal of revisions and, based on the cursor, determines whether the respective revision conflicts with revisions in the journal. When the respective revision does not conflict with revisions in the journal, the system adds the respective revision to the journal.
