Policy Name | Policy Description |
---|---|
FAIL | Fails the corresponding component. May yield failure and shutdown of the Agent |
RECOVER | Attempts to recover the affected component. If recovery isn't successful, the policy may further define routes that allow the component to transfer ownership to a new object/component. |
RETRY | Attempts to retry from the failure. May leave the agent's component in a loop |
RETRY_RECOVER | Attempts to retry the failing operation, recovery in the event that retry isn't successful. |

within failure policies that allow us to recover by resetting state or instantiating new components to take over the operation
To simply the configuration, the initial set of FailurePolicies built will allow recovery of hardware failure for repositories and network connectivity. Network connectivity is typically controlled via backpressure; however,
if network failure occurs we may want some operations to continue, thus a failure policy can recover by clearing queues or prioritizing connections.
Repositories can recover through flushing WALs, replacing WAL data, and/or converting to fully volatile repositories.
