Retry strategy for failed jobs

Variants

None

No retry attempts

Fixed

Fixed interval between retries

Fields

interval: Duration

Interval between retry attempts

max_attempts: u32

Maximum number of retry attempts

ExponentialBackoff

Exponential backoff with optional jitter

Fields

initial_delay: Duration

Initial retry delay

multiplier: f64

Multiplier for each subsequent retry

max_delay: Duration

Maximum delay between retries

max_attempts: u32

Initial retry delay

increment: Duration

Amount to add to delay for each retry

max_delay: Duration

Maximum delay between retries
