  • Patent number: 11232000
    Abstract: Replicated partitions of a database may be moved from one or more replica nodes to a different primary node. The replica nodes may maintain replicated partitions of one or more primary partitions of a primary node servicing access requests to the primary partitions. The replicated partitions may be copied to a different node in order to cause the processing of access requests directed to primary partitions to be serviced by the different node. Replicated partitions of a database may be moved from replica nodes to perform a split operation or a merger operation.

  • Patent number: 11030169
    Abstract: Processing and storage responsibility for a data set may be split according to separately stored shards of the data set. As one or more loads associated with shards of the dataset grow a re-sharding operation may be performed to reduce loading of particular shards and nodes that host the particular shards. A re-sharding operation may cause only a sub-set of as set of shards of the dataset to be split and only cause second portions of the split shards to be stored in additional computing nodes. In some embodiments, a number of shards to be included in the sub-set of shards to be split may be selected based on an overall number of shards in the set and a largest number in the Fibonacci sequence that is less than the overall number of shards in the set.

  • Patent number: 10970196
    Abstract: A database testing system may generate, based on a randomization process, test data for a database. The system may generate a query that, when processed by the database, produces a first result that comprises the row. The system may modify the query based on a randomization process and in view of the semantic properties of the query language associated with the queries. The system may predict the outcome of the modifies query based on the semantic properties and on the generated test data. The system may verify that the modified query, when processed by the database, produces results consistent with the prediction.

  • Patent number: 10929396
    Abstract: Multi-type attribute indexes may be implemented for document databases. When a request to perform a query at a document database is received that is directed toward in indexed attribute that has multiple data types for values stored in the multi-type attribute index, a predicate in the query may be replaced with a different predicate that is applicable to search the multi-type attribute index according to a sort order for the multiple data types stored in the at multi-type attribute index. A plan that includes the different predicate may be performed in order to provide a result of the query to a user.

  • Patent number: 10635336
    Abstract: A distributed system may comprise a plurality of computing nodes, each of which may provide computing capacity for operating various computing services. The system may maintain a memory-based store of records representative of capacity available on the computing nodes. A record indicative of a computing node having a requested amount of capacity may be selected. The record may be modified to indicate that the computing node is a candidate for providing the requested amount of capacity. Upon receiving information confirming that the computing node has been configured to provide the requested capacity, the record may be modified to indicate that the computing node has committed to provide the requested capacity.

  • Patent number: 10441626
    Abstract: A pharmaceutical formulation comprising a solid matrix of one or more biodegradable polymers, the solid matrix including a pharmaceutically active substance or a pharmaceutically acceptable salt thereof distributed homogeneously or substantially homogeneously within the matrix; wherein the pharmaceutically active substance is, for example, a gonadotropin releasing hormone (GnRH), a GnRH agonist or a GnRH antagonist.

  • Patent number: 10409648
    Abstract: Processing responsibility for a data set may be split according to separately stored partitions of the data set. A data set may be stored in different storage units that separately store different partitions of the data set. Mapping information may be maintained indicating the assignment of a node to process access requests to multiple partitions of a data set. A split event may be detected for the node, and one or more partitions assigned to the node may be reassigned to a different node. The storage units for the reassigned partitions may be made accessible to the different node. Then mapping information can be updated to indicate change in assignment from the original node to the different node so that the different node can begin processing access requests for the reassigned partitions.

  • Patent number: 9938922
    Abstract: A system and method for injecting fuel into an engine is provided where a low-pressure fuel pump is connected in fluid communication with at least one port fuel injector and a high-pressure fuel pump is connected in fluid communication with at least one direct fuel injector. The port fuel injector is disposed along an intake path of the engine and the direct fuel injector is disposed adjacent a cylinder of the engine. A lost motion lifter selectively couples the high-pressure fuel pump and the engine. A pump deactivation module switches the lost motion lifter to selectively deactivate the high-pressure fuel pump from the engine in response to partial load operation of the engine. The pump deactivation module may additionally switch the port fuel injector to an activated state and the direct fuel injector to a deactivated state.

  • Publication number: 20160235686
    Abstract: There is provided a supercritical fluid-based process for preparing a solid polymer matrix containing a core material, wherein the process includes the step of mixing the polymer, core material and supercritical fluid in a mixing vessel, followed at least one cycle of, without recovering the solid polymer matrix, (i) converting the supercritical fluid in the mixing vessel to a sub-critical state, and then (ii) returning the fluid to the supercritical state, provided that the core material does not comprise any of gonadotropin releasing hormone (GnRH), a GnRH agonist and a GnRH antagonist.

  • Patent number: 7832778
    Abstract: A touch bar (24) exit device (20) comprises a retractor element (50) disposed in the housing (22) for substantially restilinear movement. The retractor element (50) connects the touch bar (24) and the latch bolt (82) such that the retractor element (50) and the latch bolt (82) are moved toward the retracted position in response to movement of the touch bar (24). An electrically energizable locking mechanism (104) in the exit device (20) includes a reciprocating plunger (106) moving transverse to the retractor element (50). When energized, the locking mechanism (104) is operative to move the plunger (106) to the projected locking position to prevent retraction of the latch bolt. A time delay circuit is connected to the locking mechanism (104). A switch (120) actuated in response to movement of the touch bar (24) is connected to the time delay circuit for starting a predetermined time interval for temporarily delaying deenergization of the locking mechanism (104).
