GENERATING A PRODUCER-DRIVEN EXECUTION PLAN FROM A CONSUMER-DRIVEN ITERATOR-BASED EXECUTION PLAN

摘要

An original query execution plan of a database query is received. The original query execution plan represents a tree of operators. Source code for the original query execution plan is generated by a single traversal of the tree of operators. The generated source code is compiled into native machine code. The native machine code represents a simplified native access plan (SNAP).
