Types ¶
type DAGOperator ¶
type DAGOperator struct {
*operator.SharedOperator[DAGOperatorConfig]
// contains filtered or unexported fields
}
func NewDAGOperator ¶
func NewDAGOperator(op *sqlcv1.V1Operator, l *zerolog.Logger, repo repository.Repository, taskEventWriter operator.TaskEventWriter, opts ...DAGOperatorOpt) (*DAGOperator, error)
NewDAGOperator constructs a DAG operator. It is engine-internal: it needs the repository for the tenant's workflows and the engine-internal writer for triggering steps, so it is hosted in process only, by the claimer through the in-process host. Nothing runs until Start.
func (*DAGOperator) Drain ¶
func (d *DAGOperator) Drain(ctx context.Context)
Drain implements operator.Operator: it stops the workflow poller, interrupts the runs in flight (they leave their tasks for reassignment) and waits for them, bounded by ctx. The host has paused the worker by then, so nothing new arrives.
func (*DAGOperator) HandleAction ¶
func (d *DAGOperator) HandleAction(ctx context.Context, action *contracts.AssignedAction) error
func (*DAGOperator) Start ¶ added in v0.109.0
Start implements operator.Operator: it keeps the session, registers the tenant's DAG workflows as the worker's actions before returning so the worker is assignable at once, and starts the goroutine that keeps them in sync. The action set is data-driven, so it is refreshed on a ticker.
type DAGOperatorConfig ¶
type DAGOperatorConfig struct {
// Slots is the number of concurrent task slots the operator's worker advertises. Defaults
// to the server's configured default (WithSlots) when unset.
Slots int `json:"slots"`
}
DAGOperatorConfig is the stored config for a DAG operator. Unlike the HTTP operator, the action set is not configured statically: the operator polls the database for the tenant's DAG workflows and registers each as an action (see pollWorkflows).
type DAGOperatorOpt ¶ added in v0.104.1
type DAGOperatorOpt func(*DAGOperator)
func WithSlots ¶ added in v0.104.1
func WithSlots(defaultSlots int) DAGOperatorOpt
WithSlots sets the server-wide default slot count (SERVER_DAG_OPERATOR_DEFAULT_SLOTS) used when the operator's stored config doesn't set its own Slots.
