Class RetryConfig (2.5.0)

public sealed class RetryConfig : IMessage<RetryConfig>, IEquatable<RetryConfig>, IDeepCloneable<RetryConfig>, IBufferMessage, IMessage

These settings determine when a failed task attempt is retried.

Properties

MaxAttempts

public int MaxAttempts { get; set; }

Number of attempts per 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 >= -1.

If unspecified when the queue is created, Cloud Tasks will pick the default.

-1 indicates unlimited attempts.

This field has the same meaning as task_retry_limit in queue.yaml/xml.

Property Value
Type	Description
`Int32`

MaxBackoff

public Duration MaxBackoff { get; set; }

A task will be [scheduled][google.cloud.tasks.v2.Task.schedule_time] for retry between [min_backoff][google.cloud.tasks.v2.RetryConfig.min_backoff] and [max_backoff][google.cloud.tasks.v2.RetryConfig.max_backoff] duration after it fails, if the queue's [RetryConfig][google.cloud.tasks.v2.RetryConfig] specifies that the task should be retried.

If unspecified when the queue is created, Cloud Tasks will pick the default.

max_backoff will be truncated to the nearest second.

This field has the same meaning as max_backoff_seconds in queue.yaml/xml.

Property Value
Type	Description
`Duration`

MaxDoublings

public int MaxDoublings { get; set; }

The time between retries will double max_doublings times.

A task's retry interval starts at [min_backoff][google.cloud.tasks.v2.RetryConfig.min_backoff], then doubles max_doublings times, then increases linearly, and finally retries retries at intervals of [max_backoff][google.cloud.tasks.v2.RetryConfig.max_backoff] up to [max_attempts][google.cloud.tasks.v2.RetryConfig.max_attempts] times.

For example, if [min_backoff][google.cloud.tasks.v2.RetryConfig.min_backoff] is 10s, [max_backoff][google.cloud.tasks.v2.RetryConfig.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][google.cloud.tasks.v2.RetryConfig.max_backoff] until the task has been attempted [max_attempts][google.cloud.tasks.v2.RetryConfig.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 has the same meaning as max_doublings in queue.yaml/xml.

Property Value
Type	Description
`Int32`

MaxRetryDuration

public Duration MaxRetryDuration { get; set; }

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][google.cloud.tasks.v2.RetryConfig.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.

max_retry_duration will be truncated to the nearest second.

This field has the same meaning as task_age_limit in queue.yaml/xml.

Property Value
Type	Description
`Duration`

MinBackoff

public Duration MinBackoff { get; set; }

If unspecified when the queue is created, Cloud Tasks will pick the default.

min_backoff will be truncated to the nearest second.

This field has the same meaning as min_backoff_seconds in queue.yaml/xml.

`Duration`
