Abstract: A method for managing data storage and retrieval and operated within a database management system includes determining whether a data confidence value of a data record that is stored or is to be stored in memory of the database management system is less than a data confidence threshold, where the data confidence value includes one or more of an estimate of an accuracy of data within the data record, an estimate of the accuracy of the data record, and an estimate of a reliability level of the data. When the data confidence value is less than the data confidence threshold, the method continues by generating a confidence data record based on the data record and the data confidence value. The method continues by storing the confidence data record in memory of the database management system.

Abstract: A cluster node within a cluster of a highly parallel database system includes at least one processing unit that runs a set of first tier threads and a set of second tier threads, a storage disk drive, and a networking interface. When a first tier thread receives a task, it divides the task into a set of subtasks. The first tier thread also assigns the set of subtasks between a subset of the set of second tier threads for execution. Each second tier thread within the subset processes the one or more subtasks it is assigned to. When the task is a work, the subtasks are work units. When the task is a work unit, the subtasks are subwork units.

Abstract: A method for execution by at least one computing entity of a database system, the method includes obtaining a plurality of data partitions of a data set for storage in the database system, where the data set is organized in rows and columns, and the rows correspond to data records and the columns correspond to fields of the data records. The method further includes dividing a first partition of a plurality of data partitions to produce a first number of first raw data segments for storage in the database system, where the first number is based on a first data storage coding scheme. The method further includes dividing a second partition of the plurality of data partitions to produce a second number of second raw data segments for storage in the database system, where the second number is based on a second data storage coding scheme.

Abstract: A networked database management system (DBMS) is disclosed. In particular, the disclosed DBMS includes a plurality of nodes, one of which is elected as a designated leader. The designated leader is elected using a consensus algorithm, such as tabulated random votes, RAFT or PAXOS. The designated leader is responsible for managing open coding lines, and determining when to close an open coding line.

Abstract: A method for execution by a computer of a database management system includes obtaining a dataset that includes a set of data records, where the data set is associated with a set of data characteristics. The method further includes ranking analytical calculations of a list of analytical calculations that are able to be executed on the dataset based on the set of data characteristics and a set of analytical calculation characteristics associated with the list of analytical calculations to produce a ranked list of analytical calculations. The method further includes selecting an analytical calculation from the ranked list of analytical calculations based on the ranking. The method further includes executing the selected analytical calculation on the dataset to produce an analytical calculation result.

Abstract: A method includes obtaining a plurality of data partitions of a data set for storage in a database system. The method further includes determining a first data storage coding scheme for a first partition of the plurality of data partitions, where the first data storage coding scheme includes first encoding parameters regarding encoding the first partition into first data segments and first parity segments. The method further includes determining a second data storage coding scheme for a second partition of the plurality of data partitions. The method further includes dividing the first partition to produce a first number of first raw data segments, where the first number is based on the first data storage coding scheme. The method further includes dividing the second partition to produce a second number of second raw data segments, where the second number is based on the second data storage coding scheme.

Abstract: A method by one or more processing units of a database management system includes determining to transition a collection of data from storage in a set of first temperature storage nodes to storage in a set of second temperature nodes based on one or more criteria associated with the collection of data, where each first temperature storage node of the set of first temperature storage nodes is paired with a corresponding second temperature storage node of the set of second temperature storage nodes to form a set of parallel node pairs. The method further includes transitioning storage of the collection of data in parallel, by each parallel node pair of the set of parallel node pairs, from storage in the set of first temperature storage nodes to storage in the set of second temperature storage nodes.
