  • Database distribution system and methods for scale-out applications
    Patent number: 8620903
    Abstract: Systems and method are disclosed for query optimization in a scale-out system with a single query processing machine and a distributed storage engine to store data by receiving a query rewritten for an internal schema; optimizing a query execution plan for the query; and executing the plan and returning result to an application.
    Type: Grant
    Filed: August 31, 2010
    Date of Patent: December 31, 2013
    Assignee: NEC Laboratories America, Inc.
    Inventors: Junichi Tatemura, Arsany Sawires, Oliver Po, V. Hakan Hacigumus
  • System and methods for database distribution and querying over key-based scalable storage
    Patent number: 8380738
    Abstract: A system includes one or more application nodes sending SQL queries to one or more query execution nodes. Each query execution node translates the SQL queries into key-based requests to the storage engine, which comprises one or more storage nodes. The system provides an abstraction layer with an external schema and an internal schema, maps the external schema into the internal schema; and generates one or more microshards for the storage node.
