README.md

Contains query planning functionality on top of Query Tree, see src/Analyzer/README.md.

This component is responsible for query planning only if the enable_analyzer setting is enabled. Otherwise, the old planner infrastructure is used. See src/Interpreters/ExpressionAnalyzer.h and src/Interpreters/InterpreterSelectQuery.h.

The PlannerActionsVisitor builds ActionsDAG from an expression represented as a query tree. It also creates unique execution names for all nodes in the ActionsDAG, i.e., constants. It is responsible for creating the same execution names for expression on initiator and follower nodes during distributed query execution.

The PlannerExpressionAnalysis.h contains the buildExpressionAnalysisResult function to calculate information about the stream header after every query step.

PlannerContext contains the proper query Context and is responsible for creating unique execution names for ColumnNode. TableExpressionData for table expression nodes of the corresponding query must be registered in the PlannerContext.

Other files contain the implementation of query planning for different parts of the query.
