Types

type DiffOpSpec added in v0.175.0 

type DiffOpSpec struct{}

func (*DiffOpSpec) Kind added in v0.175.0 

func (s *DiffOpSpec) Kind() flux.OperationKind

type DiffProcedureSpec added in v0.175.0 

type DiffProcedureSpec struct {
	plan.DefaultCost
}

func (*DiffProcedureSpec) Copy added in v0.175.0 

func (s *DiffProcedureSpec) Copy() plan.ProcedureSpec

func (*DiffProcedureSpec) Kind added in v0.175.0

type GroupOpSpec 

type GroupOpSpec struct {
	Mode    string   `json:"mode"`
	Columns []string `json:"columns"`
}

GroupOpSpec in package experimental defines a special group() function that has just one mode called "extend", which adds additional columns to the group key. This is a workaround until schema introspection is implemented:
