abstract class Policy extends AnyRef

A retry com.digitalasset.canton.util.retry.Policy defines an interface for retrying a future-based task with retry semantics specific to implementations. If the task throws a non-fatal exceptions synchronously, the exception is converted into an asynchronous one, i.e., it is returned as a failed future or retried.

If unsure about what retry policy to pick, com.digitalasset.canton.util.retry.Backoff is a good default.
