Working with Actions¶
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.
List Actions¶
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
Get 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())
