A method for creating a link between hyperledger blocks by a block link server. The method comprises receiving by a block link server executing on a computer system a first link creation message from a first network element, the first link creation message comprising first block information comprising a first hyperledger identifier and a first block identifier, both associated with a first hyperledger, receiving by the block link server a second link creation message, comprising second block information comprising a second hyperledger identifier and a second block identifier, both associated with a second hyperledger, storing by the block link server a link data structure comprising the first block information and the second block information, and sending by the block link server a link identifier of the link data structure to the first network element.

In some embodiments, a computer system may buffer, in a local storage buffer, data to be stored at the cloud and upload the data to the cloud storage from the local storage buffer. Upon receipt of an acknowledgement, from the cloud storage, that the data was successfully uploaded, the computer system may delete the data from the local storage buffer. The computer system may provide a ghost file representation of the uploaded data through the computer system, through which the data uploaded to the cloud storage may be accessed. In some embodiments, the computer system may access multiple cloud storage accounts, each corresponding to a file folder on the computer system, allowing the user to easily access different cloud storage accounts. The computer system may recover data that was deleted from either local persistent storage or the cloud storage.

A record linking platform having a computer system with a processor, multiple databases each having records, such as private health information. Each of the multiple databases are not in direct communication with one another. A control center is in communication with the different entities, the control center configured to: generate a site configuration file, a key configuration file, and a broker configuration file. A keymaster configured to: receive the key configuration file, generate a hash key, and transmit the hash key to the databases. The databases configured to: receive the site configuration file and the hash key; process the records to generate evaluation records data that conform to a data model specified in the site configuration file; and encrypt the evaluation records using the hash key. An honest broker configured to: receive the broker configuration file and the encrypted evaluation records; and link the encrypted evaluation records without decrypting.

A method of performing a virtual network function. The method comprises forking a user plane process on a computer by a virtual network function process that executes on the computer, forking a control plane process on the computer by the virtual network function process, adding blocks to a user plane blockchain by the user plane process that record user plane events, adding blocks to a control plane blockchain by the control plane process that record control plane events, creating a first package of information by the user plane process based on the user plane blockchain, self-terminating by the user plane process while passing the first package of information to the virtual network function process, creating a second package of information by the control plane process based on the control plane blockchain, self-terminating by the control plane process while passing the second package of information to the virtual network function process.

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.

The subject technology determines, using a connection to an external data source, a set of shards stored in an external data source, the connection to the external data source being established using an external integration, the external integration including security and configuration information. The subject technology determines a set of offsets of each shard of the set of shards. The subject technology generates a query plan indicating a degree of parallelism based at least in part on a size of the set of offsets. The subject technology, based on the set of shards and the set of offsets, performs an operation on the external data source by performing, using the connection to the external data source, a write operation from a query statement on the external data source, the external data source being different than a storage platform associated with the system.

A method and system for auto live-mounting database golden copies. Specifically, the disclosed method and system entail reactively auto live-mounting golden copy databases on hosts or proxy hosts based on the operational state of one or more database hosts and/or one or more assets (or databases) residing on the database host(s). Should a database host prove to be unresponsive, through periodic monitoring, databases residing on the database host may be brought back online on a proxy database host using stored golden copies respective of the aforementioned databases. Alternatively, should a given database on any database host exhibit an operational abnormality (e.g., an error, failure, etc.), the given database may be brought back online on the database host or a proxy database host using a stored golden copy respective of the given database. Accordingly, through the disclosed method and system, database outages may be minimized.

An example method for storing data includes providing a plurality of physical storage pools, each storage pool including a plurality of storage nodes coupled to a network. The method also includes mapping a partition of a plurality of partitions to a set of physical storage pools, where each physical storage pool of the set of physical storage pools is located in a different availability zone, and the storage nodes within an availability zone are subject to a correlated loss of access to stored data. The method further includes receiving a data management request over the network, the data management request being associated with a data object. The method also includes identifying a first partition of the plurality of partitions corresponding to the received data management request and manipulating the data object in the physical storage pools mapped to the first partition in accordance with the data management request.

Systems and methods for folder synchronization and offline synchronization via a mobile platform in a web-based collaboration environment are disclosed. One embodiment includes synchronizing user selected folders and/or sub-folders via the mobile platform, using portable devices including smart phones and tablets using any mobile operating system to allow offline access. Child or sub-folders of the selected folders and/or sub-folders are automatically detected and synchronized for offline access. Any change or new content detected on the client side or on the server side is also synchronized such that the selected folders and/or sub-folders on the client and server sides are up to date.

A method and system for eliminating the redundant allocation and deallocation of special data on disk, wherein the redundant allocation and deallocation of special data on disk is eliminated by providing an innovate technique for specially allocating special data of a storage system. Specially allocated data is data that is pre-allocated on disk and stored in memory of the storage system. “Special data” may include any pre-decided data, one or more portions of data that exceed a pre-defined sharing threshold, and/or one or more portions of data that have been identified by a user as special. For example, in some embodiments, a zero-filled data block is specially allocated by a storage system. As another example, in some embodiments, a data block whose contents correspond to a particular type document header is specially allocated.
