5 results about "Parallel database" patented technology

A database system includes an analytics sub-system of an administrative sub-system and a parallelized query and results sub-system. The analytics sub-system includes a data management module operable to obtain and store user profile data related to end users of the database system, data provider profile data related to data providers of the database system, database usage data related to one or more current or past queries on the database system, and an analytics processing module operable to obtain query and results information from the parallelized query and results sub-system based on an analysis indication of a query, obtain analysis information from the data management module related to the query and results information, and compare the query and results information and the analysis information in light of the analysis indication to produce an analysis result.

A query and response sub-system of a parallelized database system includes a set of query and response computing nodes of pluralities of query and response computing nodes od pluralities of computing device clusters of a parallelized database system is operable to obtain a plurality of queries, determine a set of common segment query operations of pluralities of query operations of the plurality of queries, determine a set of unique segment query operations of the pluralities of query operations, determine a set of input / output (I / O) query execution plans for the set of queries based on the set of common segment query operations and the set of unique segment query operations, and determine a schedule to execute steps of the set of I / O query execution plans based on query priority of the set of queries and processing core resource availability of pluralities of storage computing nodes.

A parallelized data input sub-system of a database system includes pluralities of processing core resources of pluralities of loader nodes of pluralities of computing devices of a plurality of computing device clusters. A first set of loader nodes of the pluralities of loader nodes is operable to ingest a plurality of datasets, determine a first set of processing core resources of the pluralities of processing core resources for ingesting the first dataset, determine a second set of processing core resources of the pluralities of processing core resources for ingesting the second dataset, direct, via first routing data, the first dataset to the first set of processing core resources, for temporary storage as a first set of pages, and direct, via second routing data, the second dataset to the second set of processing core resources for temporary storage as a second set of pages.

This invention belongs to the field of database high availability design technology, specifically providing a method and system for achieving high availability of large-scale parallel databases. The method includes the following steps: installing persistent memory devices on all nodes and configuring persistent memory parameters in the operating system; installing a network interface card supporting the RDMA protocol on the coordinating node and configuring the network interface card parameters in the operating system; setting up an RDMA interface in the metadata management module of the coordinating node; when the coordinating node receives a data write request, configuring the persistent memory interface to write the data to the persistent memory device of the compute node and writing the metadata file location data to the MPP library file manager; when the coordinating node receives a read request, configuring a read interface to read the relevant data; when coordinating nodes synchronize metadata files, enabling the RDMA protocol and calling the RDMA interface set by the metadata management module to transfer the metadata files. This improves the speed of data synchronization and transmission.
