RetryConfig(mapping=None, *, ignore_unknown_fields=False, **kwargs)
Settings that determine the retry behavior.
By default, if a job does not complete successfully (meaning that an acknowledgement is not received from the handler, then it will be retried with exponential backoff according to the settings in RetryConfig.
Attributes
Name | Description |
retry_count |
int
The number of attempts that the system will make to run a job using the exponential backoff procedure described by max_doublings. The default value of retry_count is zero. If retry_count is zero, a job attempt will *not* be retried if it fails. Instead the Cloud Scheduler system will wait for the next scheduled execution time. If retry_count is set to a non-zero number then Cloud Scheduler will retry failed attempts, using exponential backoff, retry_count times, or until the next scheduled execution time, whichever comes first. Values greater than 5 and negative values are not allowed. |
max_retry_duration |
The time limit for retrying a failed job, measured from time when an execution was first attempted. If specified with retry_count, the job will be retried until both limits are reached. The default value for max_retry_duration is zero, which means retry duration is unlimited. |
min_backoff_duration |
The minimum amount of time to wait before retrying a job after it fails. The default value of this field is 5 seconds. |
max_backoff_duration |
The maximum amount of time to wait before retrying a job after it fails. The default value of this field is 1 hour. |
max_doublings |
int
The time between retries will double max_doublings
times.
A job's retry interval starts at
min_backoff_duration,
then doubles max_doublings times, then increases
linearly, and finally retries retries at intervals of
max_backoff_duration
up to
retry_count
times.
For example, if
min_backoff_duration
is 10s,
max_backoff_duration
is 300s, and max_doublings is 3, then the a job will
first be retried in 10s. The retry interval will double
three times, and then increase linearly by 2^3 \* 10s.
Finally, the job will retry at intervals of
max_backoff_duration
until the job has been attempted
retry_count
times. Thus, the requests will retry at 10s, 20s, 40s, 80s,
160s, 240s, 300s, 300s, ....
The default value of this field is 5.
