US Patent 10268704 Partitioned distributed database systems, devices, and methods

A client system can improve processing speeds by executing queries locally. A remote database can have a partitioned, columnar database. Queries from the client can be executed on the remote database, and blocks of a partition of the partitioned, columnar database can be sent to the client. Once the client has enough blocks to form the partition, the client can execute queries that reference the partition. The queries can be executed using templates for specialized expression evaluators.
