REMOTE-KEY BASED MEMORY BUFFER ACCESS CONTROL MECHANISM

摘要

Techniques for processing a query are provided. One or more operations that are required to process a query are performed by a coprocessor that is separate from a general purpose microprocessor that executes query processing software. The query processing software receives a query, determines one or more operations that are required to be executed to fully process the query, and issues one or more commands to one or more coprocessors that are programmed to perform one of the operations, such as a table scan operation and/or a lookup operation. The query processing software obtains results from the coprocessor(s) and performs one or more additional operations thereon to generate a final result of the query.
