A method for enabling pruning of a blockchain of a blockchain network includes creating an active blocks commitments Merkle tree from hashes of active blocks and creating an active smart contracts commitments Merkle tree from hashes of active smart contracts. The Merkle trees are created after an amount of blocks created in the blockchain has reached a threshold set by a pruning threshold parameter stored in the blockchain network. Hashes of the roots of the Merkle trees are stored in a header of a new block as a new genesis block. The new genesis block is broadcast to the blockchain network. A set of the active blocks and active smart contracts used respectively to create the active blocks commitments Merkle tree and the active smart contracts commitments Merkle tree are committed to upon the blockchain network reaching consensus on the new genesis block.

Techniques for monitoring local and/or remote file systems by a synchronization component (e.g., client/server) of a cloud-based platform are disclosed. In some embodiments, a method of building synchronization events by a synchronization component (e.g., a synchronization server/client) includes obtaining a set of items that have been changed and their new states and retrieving last known states of the set of items that are stored in a reference snapshot inside a filesystem scanner. The method further includes generating differences between the new states and the last known states of the set of items as item changes and utilizing information provided by the item changes to translate the item changes into synchronization events for execution on the opposing file system. A method of handling failed synchronization events by a synchronization component of the cloud-based platform by collapsing a subsequent event with the failed synchronization event is also disclosed.

In an embodiment, a data processing method comprises detecting an approval of a change to an electronic configuration document that symbolically identifies one or more configurations of users, groups, and/or permissions relating to access to computer program artifacts that are stored in a first repository of a geographically distributed, replicated artifact repository system; the artifact repository system comprising one or more second repositories that are geographically remote with respect to the first repository and which replicate the first repository; in response to the detecting: obtaining the electronic configuration document and deriving, based on the electronic configuration document, a plurality of regional repository settings values for users, groups, and/or permissions relating to access to the computer program artifacts and for the one or more second repositories; transmitting the one or more settings values to the one or more second repositories and causing injection of the one or more settings values into one or more repository configuration settings of the second repositories.

Various systems and methods are provided in which a replication process is initiated between a primary site and a recovery site, each having plurality of gateway appliances. Replication loads are evaluated for each given gateway appliance of the plurality of gateway appliances. If a determination is made that at least one gateway appliance of the plurality of gateway appliances is not overloaded, the plurality of gateway appliances are sorted based on replication loads respectively associated with each gateway appliance, and a determination is made as to whether a relative difference in replication loads between a gateway appliance having a highest replication load and a gateway appliance having a lowest replication load exceeds a difference threshold to determine whether the replication workloads between the gateway appliances should be rebalanced.

A computer-implemented method may comprise executing, by a first plurality of replicated state machines, a sequence of ordered agreements to make mutations to a data stored in a first data storage of a first type and executing, by a second plurality of replicated state machines, the sequence of ordered agreements to make mutations to the data stored in a second data storage of a second type. First metadata of the mutated data stored in the first data storage may then be received and stored, as may second metadata of the mutated data stored in the second data storage. A comparison of the stored first and second metadata may then be carried out when the data stored in the first data storage that corresponds to the first metadata and the data stored in the second data storage that corresponds to the second metadata have been determined to have settled according to the predetermined one of the sequence of ordered agreements. A selected action may then be carried out depending upon a result of the comparison.

Techniques described herein relate to systems and methods of data storage, and more particularly to providing layering of file system functionality on an object interface. In certain embodiments, file system functionality may be layered on cloud object interfaces to provide cloud-based storage while allowing for functionality expected from a legacy applications. For instance, POSIX interfaces and semantics may be layered on cloud-based storage, while providing access to data in a manner consistent with file-based access with data organization in name hierarchies. Various embodiments also may provide for memory mapping of data so that memory map changes are reflected in persistent storage while ensuring consistency between memory map changes and writes. For example, by transforming a ZFS file system disk-based storage into ZFS cloud-based storage, the ZFS file system gains the elastic nature of cloud storage.

In some implementations, a subscriber to an online content management system can share content items that are external to the subscriber's content library. A computing device can include managed content items associated with the subscriber's content library. The computing device can include unmanaged content items that are stored externally to the subscriber's content library. The subscriber can provide input associated with an unmanaged content item to generate a link (e.g., URL, file path, location reference, etc.) for the unmanaged content item. When generating the link, the unmanaged content item can be uploaded to the online content management system and stored separately from the subscriber's content library. The generated link can be shared with recipient user (e.g., subscriber or non-subscriber). The generated link can be used by the recipient to access the unmanaged content item uploaded to and stored by the online content management system.

The operational performance and the I/O performance of Snapshots in a storage system are balanced. In a storage system, meta information of data appended to a log structured area is composed of meta information of a first tier and meta information of a second tier which correlate location information of data in a logical volume and location information of data in the log structured area. When creating a snapshot of the logical volume, a data management unit creates, in the same meta information area as a replication source, a replication of the meta information of the first tier stored in a plurality of meta information areas assigned to a plurality of controllers. A data control unit accesses the data of the log structured area from the logical volume, and accesses the data of the log structured area from the snapshot.

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.
