  • Assigning nodes to shards based on a flow graph model
    Patent number: 10776356
    Abstract: A technique includes modeling assignments of a plurality of nodes to a plurality of shards associated with a database operation based on a target throughput for the plurality of nodes. The modeling includes constraining the assignments based on an aggregate outflow from the plurality of nodes. The technique includes initializing the aggregate outflow to be less than the target throughput; and determining the assignments based on the modeling.
    Type: Grant

  • Assigning segments of a shared database storage to nodes
    Patent number: 10534765
    Abstract: A technique includes applying a first mapping to associate a plurality of data records for a plurality of database nodes with a plurality of segments of a storage that is shared by the database nodes; and applying a many-to-many second mapping to associate the segments with the database nodes.

  • GARBAGE COLLECTION BASED ON ASYNCHRONOUSLY COMMUNICATED QUERYABLE VERSIONS
    Publication number: 20180293165
    Abstract: A technique includes determining an earliest query start time associated with a plurality of queries currently being processed by a node; and based on the identified earliest query start time, selecting a version of a global catalog existing at the earliest start time. The global catalog represents objects stored in a storage shared by the node and at least one other node. The technique includes communicating the selected version of the global catalog to an object garbage collector for the storage.
