Abstract: Aspects of the disclosure are directed to generating a hybrid query execution plan for executing queries on database systems implementing a columnar cache. A hybrid query execution plan combines a query execution plan for querying and retrieving data from a columnar cache and a base table. A columnar cache stores cached data in column-major format, which is logically represented by the database management system in row-major format. A database management system as described herein can scan valid blocks of column data according to a column scan operation. The system can identify invalidated blocks and execute a different sub-execution plan of the hybrid query execution plan to scan corresponding rows in tables corresponding to the location of data for the invalidated blocks.

Abstract: A subscriber identity module (eUICC), comprises profiles for the utilization of a mobile terminal that include at least a first profile and at least a second profile, of which the second profile (Pr1, Pr2) is devised as an active profile. The first profile is designed as a root profile (PrR) which in a normal state of the subscriber identity module is in an inactive state, and which is devised to be activated in response to an authentication command (AUTHENTICATE) received at the subscriber identity module. The authentication command is specially parameterized for the root profile (PrR) with a specific root value of the network parameter (P2) to be activated during a change-over period. The initially active second profile (Pr1, Pr2) is deactivated during the change-over period. After the end of the change-over period, the first profile (PrR) is again deactivated and the second profile (Pr1, Pr2) is again activated.

Abstract: Methods and systems are described for provisioning cloud-based database systems and performing decoupled maintenance. For example, conventional systems may rely on database management systems to provision and modify databases hosted by a service provider. However, for entities operating complex database systems with the need for highly customized cloud infrastructure, database management systems fail to provide the granular customization and the control necessary to create and service these systems. In contrast, the described solutions provide an improvement over conventional database management system architecture by providing direct communication between an entity and its cloud-based database systems via command line prompts or API calls, decoupling database system maintenance from database system provisioning process to increase the speed and granular customization of the database system.

Abstract: A streaming distributed decentralized database task system can perform multiple tasks of parallel jobs on clusters of nodes without overloading the clusters' computational resources, such as disk, memory, processors, and network bandwidth. A cluster master can manage a job and add items to node queues. A node manager accepts or rejects queue items based on streaming task limits that are applied at the node level.

Abstract: An illustrative storage management appliance is interposed between client computing devices and one or more cloud storage resources. The appliance uses cloud storage resources in conjunction with a network attached storage device configured within the appliance to provide to the client computing devices seemingly unlimited network attached storage on respective network shares. The storage management appliance monitors data objects on the network shares and when a data object meets one or more criteria for archiving, the storage management appliance archives the data object to a cloud storage resource and replaces it with a stub and preview image on the network share. When access to the stub and/or preview image is detected, the storage management appliance restores the data object from the cloud storage resource. The criteria for archiving flexibly allow individual data objects to be archived to cloud storage without archiving frequently-accessed “neighboring” data objects on the same network share.

Based on the result of the comparison, the client application replaces placeholder items with content items or replaces content items with placeholder items.

A confirmation is sent to the hypervisor from the backup module indicating that a full backup of the virtual disks has been created.

Abstract: Expandable cache management dynamically manages cache storage for multiple network shares configured in a file server. Once a file is written to a directory or folder on a specially designated network share, such as one that is configured for “infinite backup,” an intermediary pre-backup copy of the file is created in an expandable cache in the file server that hosts the network share. On write operations, cache storage space can be dynamically expanded or freed up by pruning previously backed up data. This advantageously creates flexible storage caches in the file server for each network share, each cache managed independently of other like caches for other network shares on the same file server. On read operations, intermediary file storage in the expandable cache gives client computing devices speedy access to data targeted for backup, which is generally quicker than restoring files from backed up secondary copies.

In a further example, a selective synchronization dialog may be launched to allow the user specify select action(s). A policy that dictates the hydration behavior may be persisted and updated as needed. To implement the policy, required operations on the local machine may be intercepted.

Abstract: Shared content items are migrated between accounts on a content management system. Users store content items synchronized between one or more client devices and the content management system. A user may have multiple accounts including personal and organization accounts. Content items may be shared with accounts belonging to other users to enable those other users to view or manipulate the content items. A user initiates a migration of content items between accounts of different categories via a user interface, e.g., by dragging and dropping a folder from one account to another. The content management system recognizes that the user has deleted the folder from the user's first account and determines that an identical folder has been created in another account belonging to the same user. In response the content management system joins the second account to the shared folder, and removes the first account from the shared folder.

Abstract: A data storage environment can include one or more virtual clients instantiated on a host proxy computing device. The virtual clients may have only indirect access to a storage device, and my access the storage device via the proxy computing device. For example, the proxy computing device receives storage operation requests from one of the virtual clients, such as a request to create, mount or revert a snapshot of virtual client data. The proxy computing device generally acts as an intermediary between the virtual clients and the storage device to carry out the snapshots or other storage operations. The proxy computing device may further receive a notification upon completion of the storage operations, and transmits relevant data to the requesting virtual client regarding the storage operation.
