摘要： Disclosed are a method and system for implementing a distributed persistent queue. To implement the queue, an API is defined that includes a command to enqueue an object onto the queue, to obtain the ordering of all objects in the queue and to remove any item from the queue. Enqueuing an object includes obtaining a unique ID for the object from a generator and then storing the object in a persistent shared log, which provides persistent storage for the queue. Obtaining an ordering of all objects in the persistent queue includes receiving for each object stored in the queue a pair of values, the first being the unique ID and the second being a sequence number from the persistent shared log. Regardless of the host computer system making the request for the ordering of objects in the queue the ordering provided to each host computer system is the same.

摘要： Methods for use in a dispersed storage network (DS) to determine appropriate resources for storing data. An example method, implemented by one or more devices of a dispersed storage network (DSN), includes obtaining storage characteristics relating to data stored in a first pool of storage units associated with a first storage tier, the data stored as a set of encoded data slices. Based on the storage characteristics, the method determines to move the data to a target storage pool of storage units associated with a second storage tier. The method also determines whether to re-encode the data for storage in the target storage pool of storage units. When not re-encoding the data, the method includes retrieving the set of encoded data slices, translating associated slice names into translated slice names, and facilitating storage of the encoded data slices in the target storage pool utilizing the translated slice names.

摘要： A method of restoring version data stored across two or more cloud environments is provided. An example method includes accessing, in a second cloud environment, first metadata describing a first data version, the first data version including first data items and first metadata, wherein at least the first data items are stored in a first cloud environment and the first metadata is stored in a third cloud environment. In response to an instruction received in the second cloud environment, the first data items are restored to the second cloud environment using the first metadata.

摘要： A method and system for incrementally revising designated portions of content contained in a medium to provide a new edition and/or a revised edition of the medium, the method including assigning a unique identifier to each element of the content contained in the source version; creating for each element of the content, at least one of a change set file, a logical content store file, or a definition file; receiving from a first author a first modification to a discrete portion of the content, the first modification further comprising: a logical intent of the first author for the first modification, a purpose of the first author for the first modification, or a goal of the first author for the first modification; storing the first modification in a corresponding first change set file; receiving from a second author a second modification to the discrete portion of the content, the second modification further comprising: a logical intent of the second author for the second modification, a purpose of the second author for the second modification, or a goal of the second author for the second modification; storing the second modification in a corresponding second change set file; and merging the first change set file and the second change set file into the medium.

摘要： A method of collaborating in real-time via action creation, including detecting an annotation on a managed document, parsing the annotation, and generating an action record including at least one of a received client, a received matter, and a received project, a received action to be performed, and an assigned user to perform the received action being a user of the plurality of users. The method further includes recording a generated action record an action database.

摘要： Techniques index a file. The techniques involve: determining, based on a first mapping stored in a first inode associated with the file, whether a predetermined conversion condition is satisfied. The first mapping points to a plurality of data blocks of a file system storing the file in a first index structure. The techniques further involve, in response to determining that the predetermined conversion condition is satisfied, creating a second inode associated with the file. The techniques further involve converting the first mapping into a second mapping to be stored in the second inode. The second mapping points to the plurality of data blocks in a second index structure different from the first index structure.

摘要： 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.

摘要： Embodiments of the invention are directed to a decentralized block chain regulation architecture. The invention utilizes the collective nature of block chain communication to perform key regulatory and control functions. Instead of relying on a centralized regulatory source, the present system allows the block chain structures themselves to simultaneously function as both regulated and regulatory chains for one another to form an interconnected network of decentralized, regulatory chains. Further, the system allows for control of non-compliant block chains, wherein regulatory chains may issue commands to the non-compliant chains, rewrite data, overwrite an incorrect consensus, or deactivate a chain and remove it from a block chain environment before propagation of an error.
