Abstract: A system and method for exposing volumes with underlying read-write mediums to user operations. When a medium is in the process of being replicated to a storage array, a volume which relies on the medium can be exposed to user operations (e.g., snapshots, read and write operations) once the portions of the medium which underlie the volume have been replicated. The volume can be exposed to user operations while one or more other portions of the medium are unfilled and while the medium is in an intermediate read-write state.

Abstract: A file management method and a file system are applied to the field of data processing technologies. The file system monitors input/output (IO) access information for operating a file, then determines an IO access mode of the file, determines a corresponding file management policy according to the IO access mode, and finally, when the obtained file management policy is inconsistent with a current management manner of the file, adjusts, according to the determined file management policy, the current management manner of the file, for example, a storage medium and a file management granularity, so as to dynamically adjust the storage medium and the file management granularity of the file according to the IO access mode of the file.

Abstract: A method implemented by a computer with a processor and a memory storing instructions executed by the processor includes receiving a query with a search region and a predicate. The search region is mapped to a set of blocks. For each block in the set of blocks, ellipsoidal geographic coordinates of the search region are transformed to flat coordinates. Results are retrieved from a primary index when the block does not contain a boundary of the search region. Results are retrieved from a secondary index when the block does contain a boundary of the search region. Retrieving results from the secondary index includes processing the boundary and the predicate against the secondary index.

Abstract: Various systems and methods for modifying the contents of a snapshot after the snapshot has been created are disclosed. One such method involves attaching a volume filter driver to a snapshot volume. The method detects one or more modifications intended for data in a read-only snapshot. Upon detecting the modification(s) intended for data in the read-only snapshot, the method performs a write operation, which includes the modification(s), to a secondary storage device instead of a primary storage device.

Abstract: The disclosure relates to a system comprising a first and a second database engine and a replication module. The replication module replicates changes from a first database maintained by the first engine to a second database maintained by the second engine. The system maps state times and sync times. The state times are specified in a first temporal reference system used by the first engine and the sync times are specified in a second temporal reference system used by the second engine. Each mapped state time and sync time pair indicate an identical state of the first and second database or parts thereof. The system executes a query partially by the first and partially by the second engine and uses the mapping to execute the query by the first and/or second engine on data of a single defined state.

Abstract: A method and system uses a probabilistic topic model to identify topics that are relevant search query terms received by a customer support system from a user, according to one embodiment. The probabilistic topic model identifies topics that are relevant to the search query terms at least partially based on the context around the receipt of the search query terms, according to one embodiment. By identifying relevant topics at least partially based on the context around the receipt of the search query terms, a likelihood of inaccurately identifying a relevant topic is reduced, according to one embodiment.

Abstract: Various embodiments describe multi-site cluster-based data intake and query systems, including cloud-based data intake and query systems. Using a hybrid search system that includes cloud-based data intake and query systems working in concert with so-called “on-premises” data intake and query systems can promote the scalability of search functionality. In addition, the hybrid search system can enable data isolation in a manner in which sensitive data is maintained “on premises” and information or data that is not sensitive can be moved to the cloud-based system. Further, the cloud-based system can enable efficient leveraging of data that may already exist in the cloud.

Abstract: Various embodiments of systems and methods to control interactions between an application user interface and a database are described herein. In one aspect, a secondary persistency of application data is generated based on a primary persistency of the application data in a database. A request to modify a value of a field of the application data in the secondary persistency is received from the application user interface. The field of the application data in the secondary persistency is updated in response to the received request for modification. A determination is made that the received request for modification influences other fields of the application data according to a set of rules. The other fields of the application data are updated based on the received request. The application data in the secondary persistency is then transitioned to the primary persistency upon request.

Abstract: An indexing system indexes data entries in a database and processes queries of the database. The indexing system generates a key database storing keys that each represent a vector of a relative attribute between two data entries. For instance, a temporal distance indicates a relative time between timestamps of events represented by the two data entries. In other embodiments, relative attributes may be based on physical proximity, altitude, semantics, etc. The indexing system may also generate a key space database to enable efficient lookup of events associated with a target entity for indexing new data entries. For example, the indexing system may perform one read operation using the key space database to lookup all events associated with the target entity. Furthermore, the indexing system may determine responses for queries to retrieve events that occurred within a target temporal distance before or after a target type of event.
