DataFlowExecutor

Abstract Value Members

abstract def flowReporter: FlowReporter

Used to report events on the flow.
abstract def initActionScheduler(): ActionScheduler

Action scheduler used to run actions
abstract def priorityStrategy: priorityStrategy

A complex data flow has lots of parallel, diverging and converging actions, lots of the actions could be started in parallel, but certain actions if started earlier could lead to quicker end to end execution of all of the flows and various strategies could lead to it.
A complex data flow has lots of parallel, diverging and converging actions, lots of the actions could be started in parallel, but certain actions if started earlier could lead to quicker end to end execution of all of the flows and various strategies could lead to it. This strategy will always be applied to a set of actions to schedule regardless of the scheduler implementation.

def execute[A <: DataFlow[A]](dataFlow: A, errorOnUnexecutedActions: Boolean = true): (Seq[DataFlowAction], A)

Executes as many actions as possible with the given DAG, stops when no more actions can be executed.
Executes as many actions as possible with the given DAG, stops when no more actions can be executed.
dataFlow
initial state with actions to execute and set inputs from previous actions
errorOnUnexecutedActions
whether to throw an exception if some actions on the flow did not execute. Default is true
returns
(Seq[EXECUTED ACTIONS], FINAL STATE). Final state does not contain the executed actions and the outputs of the executed actions are now in the inputs

def nextActionToSchedule[A <: DataFlow[A]](currentFlow: A, actionScheduler: ActionScheduler): Option[(String, DataFlowAction)]

Determines which execution pool to schedule in and an action to schedule into it.
Determines which execution pool to schedule in and an action to schedule into it. Decision depends on: 1) slots available in the pools 2) actions available for the pools with slots 3) priority strategy that will select and change the order of the available actions
returns
(Pool into which to schedule, Action to schedule)
