class dataikuapi.dss.scenario.DSSScenario(client, project_key, id)#

A handle to interact with a scenario on the DSS instance.

Important

Do not instantiate directly, use dataikuapi.dss.project.DSSProject.get_scenario()

abort()#

Abort the scenario.

This method does nothing if the scenario is not currently running.

run_and_wait(params=None, no_fail=False)#

Request a run of the scenario and wait the end of the run to complete.

The method requests a new run, which will start after a few seconds.

Parameters:

params (dict) – additional parameters that will be passed to the scenario through trigger params (defaults to {})
no_fail (boolean) – if False, raises if the run doesn’t end with a SUCCESS outcome

Returns:

a handle on the run

Return type:

DSSScenarioRun

run(params=None)#

Request a run of the scenario.

The method requests a new run, which will start after a few seconds.

Note

This method returns a trigger fire, NOT a Scenario run object. The trigger fire may ultimately result in a run or not.

Usage example:

scenario = project.get_scenario("myscenario")
trigger_fire = scenario.run()

# When you call `run` a scenario, the scenario is not immediately
# started. Instead a "manual trigger" fires.
# 
# This trigger fire can be cancelled if the scenario was already running,
# or if another trigger fires. Thus, the scenario run is not available 
# immediately, and we must "wait" for it
scenario_run = trigger_fire.wait_for_scenario_run()

# Now the scenario is running. We can wait for it synchronously with
# scenario_run.wait_for_completion(), but if we want to do other stuff
# at the same time, we can use refresh
while True:
    scenario_run.refresh()
    if scenario_run.running:
        print("Scenario is still running ...")
    else:
        print("Scenario is not running anymore")
        break

    time.sleep(5)

Params dict params:: additional parameters that will be passed to the scenario through trigger params (defaults to {})
Returns:: a request for a run, as a trigger fire object
Return type:: DSSTriggerFire
