METHODS OF MICRO-SPECIALIZATION IN DATABASE MANAGEMENT SYSTEMS
摘要
Systems and methods for utilizing relation- and query-specific information to specialize DBMS code at runtime based on identifying runtime locally invariant variables. Runtime invariant is often of the form of variables in code that hold values that are constant during a portion of code execution. Micro-specialization is applied to eliminate from the original program unnecessary code such as branching statements that reference local invariant(s) in branch-condition evaluation. The resulting specialized code reduces the code complexity as well as significantly improves the runtime efficiency during code execution.
