Constants
TYPE_UNKNOWN
value: 0
Default type for the enum. Value should never be returned.
TARGET_NUM_WORKERS_CHANGED
value: 1
The TARGET_NUM_WORKERS_CHANGED type should be used when the target
worker pool size has changed at the start of an actuation. An event
should always be specified as TARGET_NUM_WORKERS_CHANGED if it reflects
a change in the target_num_workers.
CURRENT_NUM_WORKERS_CHANGED
value: 2
The CURRENT_NUM_WORKERS_CHANGED type should be used when actual worker
pool size has been changed, but the target_num_workers has not changed.
ACTUATION_FAILURE
value: 3
The ACTUATION_FAILURE type should be used when we want to report
an error to the user indicating why the current number of workers
in the pool could not be changed.
Displayed in the current status and history widgets.
NO_CHANGE
value: 4
Used when we want to report to the user a reason why we are
not currently adjusting the number of workers.
Should specify both target_num_workers, current_num_workers and a
decision_message.
