Functions

func Call

func Call(idx int, proc *process.Process, argument any, isFirst bool, isLast bool) (process.ExecStatus, error)

Call is the execute method of minus operator it built a hash table for right relation first. use values from left relation to probe and update the hash table. and preserve values that do not exist in the hash table.

func Prepare

func Prepare(proc *process.Process, argument any) error

func String

func String(_ any, buf *bytes.Buffer)

Types

type Argument

type Argument struct {

	// hash table bucket related information.
	IBucket, NBucket uint64
	// contains filtered or unexported fields
}

func (*Argument) Free

func (arg *Argument) Free(proc *process.Process, pipelineFailed bool, err error)
