Abstract: Systems and methods are disclosed for receiving, at query coordinator, a search query. The query coordinator parses the search query and generates tasks for different runtime systems. The query coordinator configures an interface enabling inter system communication between the runtime systems. The generated tasks are distributed to the runtime systems and partial results of a runtime system are communicated to the interface. The query coordinator retrieves the partial results from the interface, finalizes the partial results, and sends finalized results them to the requestor of the search query.

Abstract: Systems and methods are described for implementing programmatic input/output (I/O) routing to datasets with user-defined partitions while providing unhandled data protection. As disclosed herein, a user may define a dataset as including one or more partitions, each partition including criteria for storing data objects written to the partitioned dataset in the individual partitions. Data objects written to the dataset can then be evaluated according to the criteria, and routed to an appropriate partition. To provide unhandled data protection, a dataset definition can include a default partition to which data objects are routed when the data object fails to satisfy the criteria of any of the set of user-defined partitions identified in the specification. Processing I/O operations according to a user-defined partitioning schema can enable data objects to be arranged according to any partitioning schema without tethering the partitioning to a particular underlying storage system.

Abstract: Systems and methods are described for providing previews of deployment of data stream processing instructions sets, sometimes called pipelines, to a stream data processing system. Rather than deploying such an instruction set, which may cause detrimental side effects, previews can be facilitated by conversion of a data stream processing instructions set to a batch query that is applied to an existing data set. An output of the batch query can then be provided to an end user as a preview of output of the data stream processing instructions set, when implemented.

Abstract: Identifying a set of information sources from a plurality of N diverse information sources, then, responsive to user input, retrieving a first set of data items from a first information source after determining a first extent of information retrieval, and retrieving a second set of data items from the second information source after determining a second extent of information retrieval and so on for all of the N diverse information sources. The extents of the retrieval comprise at most a number of data items specified by a user (e.g., corresponding to a page size). The method continues by sorting all of the N set of data items fetched from the diverse sources in Round Robin fashion until at least a specific number of elements are merged for generating a paged, sorted set of data items to be displayed in a paginated format.
