RetryConfig(mapping=None, *, ignore_unknown_fields=False, **kwargs)Retry config. These settings determine how a failed task attempt is retried.
This message has oneof_ fields (mutually exclusive fields).
For each oneof, at most one member field can be set at the same time.
Setting any member of the oneof automatically clears all other
members.

Attributes
| Name | Description |
max_attempts |
int
The maximum number of attempts for a task. Cloud Tasks will attempt the task max_attempts times
(that is, if the first attempt fails, then there will be
max_attempts - 1 retries). Must be > 0.
This field is a member of oneof_ num_attempts.
|
unlimited_attempts |
bool
If true, then the number of attempts is unlimited. This field is a member of oneof_ num_attempts.
|
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 will be made and the task will be
deleted.
If zero, then the task age is unlimited.
If unspecified when the queue is created, Cloud Tasks will
pick the default.
This field is output only for [pull
queues][google.cloud.tasks.v2beta2.PullTarget].
max_retry_duration will be truncated to the nearest
second.
This field has the same meaning as `task_age_limit in
queue.yaml/xml |
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. If unspecified when the queue is created, Cloud Tasks will pick the default. This field is output only for [pull queues][google.cloud.tasks.v2beta2.PullTarget]. min_backoff will be truncated to the nearest second.
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. If unspecified when the queue is created, Cloud Tasks will pick the default. This field is output only for [pull queues][google.cloud.tasks.v2beta2.PullTarget]. max_backoff will be truncated to the nearest second.
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.
This field is output only for [pull
queues][google.cloud.tasks.v2beta2.PullTarget].
This field has the same meaning as `max_doublings in
queue.yaml/xml |
