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.

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 |
google.protobuf.duration_pb2.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 |
google.protobuf.duration_pb2.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 |
google.protobuf.duration_pb2.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 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.
