  • Parallel batch metadata transfer update process within sharded columnar database system
    Patent number: 11010367
    Abstract: A database management system includes a cluster of nodes over which a columnar database has been sharded into shards to which the nodes are subscribed. Source nodes of the cluster store up-to-date metadata objects for the shards, and target nodes of the cluster storing out-of-date metadata objects for the shards. A coordinator node initiates a parallel batch metadata transfer update process in which the out-of-date metadata objects at the target nodes are updated in parallel from the up-to-date metadata objects at the source nodes. The coordinator node can determine pairs of source nodes and target nodes; the source node and the target node of each pair respectively store an up-to-date metadata object and an out-of-date metadata object for a same shard.

  • PROCESSING QUERIES ASSOCIATED WITH MULTIPLE FILE FORMATS BASED ON IDENTIFIED PARTITION AND DATA CONTAINER OBJECTS
    Publication number: 20200250192
    Abstract: A technique includes providing, by a computer, a request for a set of at least one partition object based on a query to a database table. The database table has an associated dataset, the query identifies a plurality of columns, and the partition object is associated with a column-based partition of the dataset.
