    摘要： A KVS tree database and operations thereon are described herein. A KVS tree database is a multilevel tree that includes a base level and subsequent levels. The base level includes a heterogeneous kvset in a node, The heterogeneous kvset including entries for multiple KVS trees, such as a first entry for a first KVS tree and a second entry for a second KVS tree, The subsequent level includes a first node including a first homogeneous kvset for the first KVS tree and a second node including a second homogeneous kvset for the second KVS tree. Here, a homogeneous kvset includes nodes from only one KVS tree. The KVS tree database also includes a first determinative mapping of entries between the base level and the subsequent level and a second determinative mapping of entries between subsequent levels.

    摘要： Systems and techniques for reducing probabilistic filter query latency are described herein. A query for a probabilistic filter that is stored on a first media may be received from a caller. In response to receiving the query, cached segments of the probabilistic filter stored on a second media may be obtained. Here, the probabilistic filter provides a set membership determination that is conclusive in a determination that an element is not in a set. The query may be executed on the cached segments resulting in a partial query result. Retrieval of remaining data of the probabilistic filter from the first media to the second media may be initiated without intervention from the caller. Here, the remaining data corresponds to the query and data that is not in the cached segment. The partial query results may then be returned to the caller.

    摘要： A cleaning apparatus for cleaning a surface in which cleaning solution is dispensed to the surface and substantially simultaneously extracted along with the dirt on the surface in a continuous operation is provided. In one aspect of the invention, the cleaning apparatus includes a housing and a recovery tank removably mounted to the housing. A solution tank for supplying a flow of cleaning solution to the surface is removably mounted to the housing. A suction nozzle is secured to the housing and is in fluid communication with the recovery tank. A suction source is in fluid communication with the suction nozzle for generating suction to draw dirt and liquid through the suction nozzle and into the recovery tank. A first latch is operatively connected to the solution tank to releasably latch the solution tank to the housing and a second latch is operatively connected to the recovery tank to releasably latch the recovery tank to said housing, wherein the second latch is in close proximity to the first latch.

    摘要： Embodiments of the present invention provide systems and methods for applying policies at a database appliance. The database appliance, according to one embodiment, can receive a database request and determine a set of information related to the request. The information related to the request can include information, such as metadata, defined at information systems external to the database server to which the request is directed. Policies can be applied in terms of the information related to the request. By leveraging information systems, embodiments of the present invention allow policies to be applied to account for the networked environment.
