RetryConfig

data class RetryConfig(val maxAttempts: Int? = null, val initialDelay: Duration? = null, val maxDelay: Duration? = null, val backoffFactor: Double? = null, val jitter: Double? = null, val exceptions: List<String>? = null)

How a node is retried when it raises. Every property is optional: null means "unset" and falls back to the matching DEFAULT_ constant when the retry is computed, except exceptions, which has no default. Unset is kept distinct from a set value rather than resolved at construction, so a policy declared with field presence carries the same meaning here as where it was declared.

Properties

backoffFactor

val backoffFactor: Double?

Multiplier applied to the delay after each attempt.

exceptions

val exceptions: List<String>?

Reported type names to retry on, matched exactly with no subclass match. The reported name is the failure's own simple name, or for a NodeExecutionException the wrapped failure's type name -- so list e.g. "RuntimeError", not "NodeExecutionException". Null retries any failure; an empty list retries none.

initialDelay

val initialDelay: Duration?

Delay before the first retry.

jitter

val jitter: Double?

Randomness factor, not a duration: the delay is spread over delay * (1 +/- jitter). Zero removes randomness.

maxAttempts

val maxAttempts: Int?

Attempts including the first, so 0 or 1 means no retry.

maxDelay

val maxDelay: Duration?

Ceiling on any single delay.
