Technical details and manufacturing context for Plan Generator

Definition
The Plan Generator is a critical sub-component of a Query Optimizer in database management systems. Its role is to analyze a parsed query, consider various access paths, join methods, and execution strategies, and produce one or more candidate execution plans. It works by exploring the space of possible plans, often using cost-based heuristics or rules, to propose efficient sequences of operations for retrieving and processing data as specified by the SQL query.
Working Principle
The component operates by receiving a logical query plan (a tree of relational algebra operators) from the parser/rewriter. It then applies transformation rules (e.g., join ordering, predicate pushdown, access method selection) to generate equivalent physical execution plans. It typically employs algorithms like dynamic programming or randomized search to navigate the plan space. Each generated plan is associated with estimated cost metrics (I/O, CPU, memory) for evaluation by the subsequent plan selection/cost estimation module.
