RetryConfig(mapping=None, *, ignore_unknown_fields=False, **kwargs)Retry config.
These settings determine when a failed task attempt is retried.
Attributes |

|---|---|
| Name | Description |
max_attempts |
int
Number of attempts per task, including the first attempt. (If the first attempt fails, there will be max_attempts - 1 retries.)
Must be greater than or equal to -1, which indicates
unlimited attempts.
Cloud Tasks stops retrying only when max_attempts and
max_retry_duration are both satisfied, or when the task
is successfully executed. When the task has been attempted
max_attempts times and when the max_retry_duration
time has passed, no further attempts are made, and the task
is deleted. If max_attempts is set to -1 and
max_retry_duration is set to 0, the task is retried
until the `maximum task
retention |
max_retry_duration |
google.protobuf.duration_pb2.Duration
If positive, max_retry_duration specifies the time limit
for retrying a failed task, measured from when the task was
first attempted. Once max_retry_duration time has passed
*and* the task has been attempted
max_attempts
times, no further attempts are made and the task is deleted.
A zero (0) indicates an unlimited duration, up to the
`maximum task
retention |
min_backoff |
google.protobuf.duration_pb2.Duration
A task will be scheduled for retry between min_backoff and max_backoff duration after it fails, if the queue's RetryConfig specifies that the task should be retried. The value must be given as a string that indicates the length of time (in seconds) followed by s (for
"seconds"). For more information on the format, see the
documentation for
Duration __.
min_backoff will be truncated to the nearest second.
If unspecified when the queue is created, Cloud Tasks will
pick the default.
This field has the same meaning as `min_backoff_seconds in
queue.yaml/xml |
max_backoff |
google.protobuf.duration_pb2.Duration
A task will be scheduled for retry between min_backoff and max_backoff duration after it fails, if the queue's RetryConfig specifies that the task should be retried. The value must be given as a string that indicates the length of time (in seconds) followed by s (for
"seconds"). For more information on the format, see the
documentation for
Duration __.
max_backoff will be truncated to the nearest second.
If unspecified when the queue is created, Cloud Tasks will
pick the default.
This field has the same meaning as `max_backoff_seconds in
queue.yaml/xml |
max_doublings |
int
The time between retries will double max_doublings
times.
A task's retry interval starts at
min_backoff,
then doubles max_doublings times, then increases
linearly, and finally retries at intervals of
max_backoff
up to
max_attempts
times.
For example, if
min_backoff
is 10s,
max_backoff
is 300s, and max_doublings is 3, then the a task will
first be retried in 10s. The retry interval will double
three times, and then increase linearly by 2^3 \* 10s.
Finally, the task will retry at intervals of
max_backoff
until the task has been attempted
max_attempts
times. Thus, the requests will retry at 10s, 20s, 40s, 80s,
160s, 240s, 300s, 300s, ....
If unspecified when the queue is created, Cloud Tasks will
pick the default.
