An action is an abstraction of some logic that can be executed by a worker thread. Most of the operations supported by Senlin are executed asynchronously, which means they are queued into database and then picked up by certain worker thread for execution.
To examine the list of actions:
def list_actions(conn):
print("List Actions:")
for actions in conn.clustering.actions():
print(actions.to_dict())
for actions in conn.clustering.actions(sort='name:asc'):
print(actions.to_dict())
When listing actions, you can specify the sorting option using the sort
parameter and you can do pagination using the limit
and marker
parameters.
Full example: manage action
To get a action based on its name or ID:
def get_action(conn):
print("Get Action:")
action = conn.clustering.get_action(ACTION_ID)
print(action.to_dict())
