  • Complex data type encoding within columnar database
    Patent number: 11327995
    Abstract: A complex data type is encoded over columns of a table of a columnar database by mapping fields of the complex data type to the columns. An optimized query can be generated for a query specifying the complex data type. The optimized query specifies the columns to which the fields specified within the query are mapped, instead of specifying the fields. The optimized query can be processed against the database in a late materialization manner to fulfill the query.
    Type: Grant

  • 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.

  • Database recovery by container
    Patent number: 10169381
    Abstract: A method includes identifying a buddy database projection that corresponds to a recovering database projection that is to be recovered to a recovering node of a database system. A source container containing data of the buddy database projection is identified on a source node of the database system, the source container being characterized by a range of epochs that includes an epoch for which data is to be recovered to the recovering node. Data is copied from the identified source container to the recovering node.

  • SEGMENTED STORAGE FOR DATABASE CLUSTERING
    Publication number: 20130166502
    Abstract: This document describes, in various implementations, segmenting data of a database cluster into a plurality of segments, the data including a plurality of tuples, each segment including at least one of the tuples, and distributing the plurality of segments among nodes of the database cluster. Rebalancing of the data of the database cluster may be achieved by copying at least one of the plurality of segments from a source node of the database cluster to a destination node of the database cluster.

  • DATABASE RECOVERY BY CONTAINER
    Publication number: 20120290540
    Abstract: A method includes identifying a buddy database projection that corresponds to a recovering database projection that is to be recovered to a recovering node of a database system. A source container containing data of the buddy database projection is identified on a source node of the database system, the source container being characterized by a range of epochs that includes an epoch for which data is to be recovered to the recovering node. Data is copied from the identified source container to the recovering node.
