  • Patent number: 11038867
    Abstract: A flexible and extensible architecture allows for secure searching across an enterprise. Such an architecture can provide a simple Internet-like search experience to users searching secure content inside (and outside) the enterprise. The architecture allows for the crawling and searching of a variety of sources across an enterprise, regardless of whether any of these sources conform to a conventional user role model. The architecture further allows for security attributes to be received at query time, for example, in order to provide real-time secure access to enterprise resources. The user query also can be transformed to provide for dynamic querying that provides for a more current result list than can be obtained for static queries.

  • Patent number: 10956417
    Abstract: Techniques are provided for scheduling data operations for a given query based upon a query-cost model that analyzes the cost of scheduling data operations based upon their operation cost and the type of resources needed for the operation. In an embodiment, a database server receives a set of operations for a query. The database server determines a set of leaf operation nodes from the set of data operations, where the set of leaf operation nodes includes operation nodes that do not depend on the execution of other nodes within the set of data operations. The database server compares operation costs between the leaf operation nodes to determine which leaf operation node to insert into a scheduled order set. The database server inserts the leaf operation node into the scheduled order set. Then the database server iteratively determines new leaf operation nodes and performs cost analysis on remaining leaf operation nodes to generate a set of scheduled data operations.

  • Patent number: 10651097
    Abstract: Methods and systems for tracking an edge ring includes capturing an edge ring identifier from a source related to the edge ring. The edge ring is inserted into a slot of an edge ring carrier, wherein the edge ring is being assigned to the edge ring carrier. The edge ring identifier is tracked to determine transfers into and out of the edge ring carrier and into and out of a processing station. The tracking of the edge ring identifier builds a metadata file that provides lifetime information regarding the edge ring.
