Functions

func Optimize

func Optimize(ctx context.Context, sctx sessionctx.Context, node ast.Node, is infoschema.InfoSchema) (plannercore.Plan, types.NameSlice, error)

Optimize does optimization and creates a Plan. The node must be prepared first.

func OptimizeExecStmt

func OptimizeExecStmt(ctx context.Context, sctx sessionctx.Context,
	execAst *ast.ExecuteStmt, is infoschema.InfoSchema) (plannercore.Plan, error)

OptimizeExecStmt to optimize prepare statement protocol "execute" statement this is a short path ONLY does things filling prepare related params for point select like plan which does not need extra things
