  • STREAM SELECTION FOR MULTI-STREAM STORAGE DEVICES
    Publication number: 20180225316
    Abstract: Systems and techniques for stream selection from multi-stream storage devices. Notification of a KVS tree write request for a multi-stream storage device is received. The notification includes a KVS tree scope corresponding to data in the write request. A stream identifier (ID) is assigned to the write request based on the KVS tree scope and a stability value of the write request. The stream ID is returned to govern stream assignment to the write request, the stream assignment modifying a write operation of the multi-stream storage device.

  • MERGE TREE MODIFICATIONS FOR MAINTENANCE OPERATIONS
    Publication number: 20180225322
    Abstract: Systems and techniques for merge tree modifications for maintenance operations are described herein. A request for a KVS tree is received. Here, the KVS tree is a data structure including nodes and the nodes include a temporally ordered sequence of kvsets that store keys in sorted order. A parameter set for the KVS tree is received. The request is executed on the KVS tree by modifying operation of the KVS tree in accordance with the parameter.

  • MERGE TREE GARBAGE METRICS
    Publication number: 20180225321
    Abstract: Systems and techniques for collecting and using merge tree garbage metrics are described herein. A kvset is created for a node in a KVS tree. Here, a set of kvset metrics for the kvset are computed as part of the node creation. The kvset is added to the node. The node is selected for a compaction operation based on a metric in the set of kvset metrics. The compaction operation is performed on the node.

  • KVS TREE
    Publication number: 20180225315
    Abstract: A KVS tree and operations thereon are described herein. A key-value set (kvset) is received to store in a key-value data structure on at least one machine readable medium. The kvset includes a mapping of unique keys to values with the keys and the values of the kvset being immutable. The key-value data structure is organized as a tree with nodes of the tree including a temporally ordered sequence of kvsets. The kvset, once received, is written to a sequence of kvsets of a root-node of the tree.

  • APPARATUS FOR LAUNCHING A BALL
    Publication number: 20170252630
    Abstract: An apparatus for launching a ball is disclosed. An embodiment of the apparatus includes a ball launching unit including a port for ejecting a ball and a support for supporting the ball launching unit. The ball launching unit is pivotably coupled to the support to permit angular adjustment of the ball launching unit about a horizontal axis of rotation to vary a launch angle of an ejected ball, and wherein the horizontal axis of rotation intersects the port.
