Abstract: A high-availability network device database synchronization technique for devices configured with multiple network controllers is disclosed. An HA database that contains information regarding a network state may not properly synchronize upon failure of a network component. For example, an HA switch typically has only two controllers, an active and a standby. If there is a loss of the active controller that causes a failover, changes in the network state may occur rapidly while the system is trying to recover (e.g., process the failover action). In part, because of the impact of the failover (e.g., failed communication paths) and rapidity of changes to network state while processing the failover, database changes may not be properly synchronized across all available database instances. Disclosed techniques provide reconciliation of database values using a mark and sweep technique on the “upside” of the failover and alter the “source of truth” for data value discrepancies.

Abstract: Remote data management, including: receiving, at a data storage service from a client device and via a remote data management application program interface (API), a data object; receiving, at the data storage service from the client device and via the remote data management API, a message including an indication of updated metadata and including an identification of a particular data object stored by the data storage service; and generating, in accordance with the updated metadata received from the client device, a modified data object that is a reduced version of the particular data object specified by the message received from the client device, wherein the reduced version of the particular data object is stored by the data storage service.

Abstract: A source system generates snapshots of collected data. The snapshots have respective associated time references. Responsive to a request from a target system for data collected over a time interval, the source system generates a subset of the data collected by determining a start snapshot and an end snapshot. The start snapshot and the end snapshot are determined as a pair of snapshots that have respective associated time references that are most closely spaced and are inclusive of the time interval. The source system determines a difference in the data included in the end snapshot and the start snapshot and provides the subset of the data as the difference in the data included in the end snapshot and the start snapshot.

Abstract: Techniques to process a query and perform a join of tables that are distributed across nodes of a network. The join can be performed by analyzing a Where clause. An active flag structure can have flag values that identify table entries satisfying criteria of the Where clause. Keys of surviving entries of a first table can be used to generate a request for a second table to be joined. The request can be for second flags for the second table when the Where clause has criteria for the second table. A response can be used to update the first flags to change a first flag to False. After updating, data can be retrieved for first flags that are True. Requests can use identifiers associated with the first table that identify a location for sending the request, e.g., using RDMA or MPI.

Abstract: A relational database system that implements persistent version storage may include an in-row module that is executable by one or more processors to implement an in-row scheme by storing in-row previous version information within a payload of a row within a database page. The relational database system may additionally include an off-row module that is executable by the one or more processors to implement an off-row scheme by storing off-row previous version information in an off-row page that is separate from the database page. The relational database system may additionally include a storage policy that defines when previous version information is stored in accordance with the in-row scheme and when the previous version information is stored in accordance with the off-row scheme. The relational database system may additionally include a cleanup module that cleans up older versions when they are deemed unnecessary by the system.

Abstract: Systems and methods are disclosed to implement a distributed query execution system that performs statistical operations on specified time windows over time-based datasets. In embodiments, the query system splits a statistical function into a set of parallel accumulator tasks that correspond to different portions of the dataset and/or function time windows. The accumulator tasks are executed in parallel by individual accumulator nodes to generate individual statistical result structures. The structures are then combined by an aggregator node to produce an aggregate result structure that indicates the results of the statistical function over the time windows. In embodiments, the accumulator and aggregator tasks are implemented and executed using a programmable task execution framework that allows developers to define custom accumulator and aggregator tasks.

The database system may further include a hardware processor configured to execute computer-executable instructions in order to: receive an update data item; identify a record corresponding to the update data item; cause an update to the record based on information included with the update data item; identify a trigger indicator corresponding to the update to the record; determine that a type of the trigger indicator matches a type of the update to the record; and generate an event notification including information included in the update.

Abstract: Storage locations in a first tier of a multi-tier storage system are allocated to a first set of data structures (e.g., inodes) in a first file set. A file that is stored in the first tier is associated with a first data structure of the first set. In response to determining that data in the file should be moved to a second tier of the multi-tier storage system, the file is associated with a second data structure in a second file set. The second data structure is allocated a storage location in the second tier. Consequently, two data structures are associated with the file. The data is copied from the first tier to the storage location in the second tier, and can be subsequently accessed using the second data structure.

Abstract: Embodiments retrieve a set of search results that have been previously identified as having at least one associated date or location. A timeline or map is displayed that visually represents the distribution of the dates or locations within the results. The timeline is displayed with a histogram graph corresponding to the number of dates in the search results at points along the timeline. The map is displayed with markers at the locations corresponding to the locations in the search results. The user can navigate the result set using the displayed timeline or map.

The plurality of levels may include a local level that includes a plurality of pods, which may be end points in the hierarchy. The data may be stored at a source pod. The request may identify a designated level in the hierarchy at which to relocate the source data. A target pod within the distributed database system may be selected. The source pod and the target pod may be located remotely from one another. The data may be replicated to the target pod via a local change bus in communication with the source pod. The local change bus may capture changes made to data stored in the source pod and transmit the captured changes to the target pod via the hierarchy.

Abstract: A massively parallel database management system includes an index store and a payload store including a set of storage systems of different temperatures. Both the stores each include a list of clusters. Each cluster includes a set of nodes with storage devices forming a group of segments. Nodes and clusters are connected over high speed links. The list of clusters within the payload store includes clusters of different temperatures. The payload store transitions data of a segment group from a higher temperature to a segment group in a lower temperature cluster in parallel. A node moves data of a segment in the higher temperature cluster to a corresponding node's segment in the lower temperature cluster. Once the data is written in the destination segment in the lower temperature cluster, the source segment is freed to store other data. The temperatures include blazing, hot, warm and cold.
