Retry: Retrying Arbitrary Computations
This library provides utilities for defining retryers, values that describe how to retry an operation. Retryers can be used to attempt some operation and retry it in the event of failure. Retryers can be composed, allowing complex retry logic to be broken down into individual components. Retryers are exceptionally useful anytime an operation has inherent dependencies on time and external systems - for example, attempting to acquire a database connection when a database might be temporarily down or not yet initialized.
