Abstract: A mechanism is provided in a data processing system comprising at least one processor and a memory comprising instructions which, when executed by the at least one processor, causes the at least one processor to implement a network protocol based file system client for read-only exports. The file system client receives a mount request to mount an export at a file system server. The file system client stores an access type of the mounted export. Responsive to the file system client receiving from a user a modification request to perform a modification on an object in the mounted export, the file system client sends an attribute check request to the file system server. Responsive to the file system client receiving a first read-only file system error from the file system server, the file system client sets a read-only file system error flag.

Abstract: 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.

Abstract: A method involves providing an information base comprising a plurality of domain-specific segments, each segment comprising a case base having cases therein and a transform base having transforms therein. Each case comprises a case antecedent and a case consequent. One or more cases are associated with one or more of transforms within the respective segment. A contextual situation falling within one of the domain-specific segments is then received and it is determined that the received contextual situation does not match the case antecedent of any of the cases within the particular domain-specific segment. One or more transforms are applied to one or more cases within the segment to create a transformed case. The transformed case has a case antecedent that matches the contextual situation and a case consequent. The case consequent of the transformed case is displayed to a user and the transformed case is stored in the case base.

The original database tables are preserved so that users can iteratively create new dynamically merged database tables by varying the parameters.

Abstract: The described embodiments set forth techniques for managing the fragmentation of files at a computing device. Specifically, the techniques involve, for a given file, analyzing different extents of the file under a “segment window” basis to identify whether a fragmentation threshold is satisfied between the extents that correspond to the scope of the segment window. In turn, for each segment window that satisfies the threshold level of fragmentation, (1) the data for the extents is copied into an allocated area of contiguous memory, and (2) the extents are updated to reference the copied data. Additionally, the original data referred to by the extents can be freed for usage within the computing device, thereby increasing storage space. In this manner, the overall fragmentation of the file is substantially reduced under the segment window basis, thereby improving the overall performance of the computing device.

Abstract: The performance and flexibility of a data intake and query system having capabilities extended by a fabric service (DFS) system can be improved with deployment on a cloud computing platform. The DFS system can extend the capabilities of a data intake and query system by leveraging computing assets from anywhere in a big data ecosystem to collectively execute search queries on diverse data systems regardless of whether data stores are internal of the data intake and query system and/or external data stores that are communicatively coupled to the data intake and query system over a network.

Abstract: The disclosed embodiments include a technique to obtain search results from the application of transformation operations on partial search results obtained from across internal and/or external data sources. Examples of transformation operations include arithmetic operations such as an average, mean, count, or the like. Examples of reporting transformations include join operations, statistics, sort, top head. Hence, the search results of a search query can be derived from partial search result rather than include the actual partial search results. In this case, the ordering of the search results may be nonessential. An example of a search query that requires a transformation operation is a “batch” or “reporting” search query. The related disclosed techniques involve obtaining data stored in the bid data ecosystem, and returning that data or data derived from that data.

Abstract: The capabilities of a data intake and query system can be improved by implementing the data fabric service (DFS) system in a co-located deployment with the data intake and query system.

Abstract: A system for reconciling object for a configuration management databases employs statistical rules to reduce the amount of manual identification required by conventional reconciliation techniques. As users manually identify matches between source and target datasets, statistical rules are developed based on the criteria used for matching. Those statistical rules are then used for future matching. A threshold value is adjusted as the statistical rules are used, incrementing the threshold value when the rule successfully matches source and target objects. If the threshold value exceeds a predetermined acceptance value, the system may automatically accept a match made by a statistical rule. Otherwise, suggestions of possibly applicable rules may be presented to a user, who may use the suggested rules to match objects, causing adjustment of the threshold value associated with the suggested rules used.
