THIS IS A TEST INSTANCE. ALL YOUR CHANGES WILL BE LOST!!!!
Failure Policies are a necessary, but rarely codified component, of deployed software systems. Command and control necessitates a strict codified scheme for failure policies within agents.
The nomenclature will represent capabilities within Apache NiFi MiNiFi C++ agents.
| Policy Name | Policy Description |
|---|---|
| FAIL | Fails the corresponding component. May yield failure and shutdown of the Agent |
| RECOVER | Attempts 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. |
Configuration
Agents can be configured through the flow. This allows the flow to define a set of update policies that control what can be changed during runtime. FailurePolicies are controller services that are inherently
linked with command and control ( but do not require it to be running ), allowing real-time change ( if update policies allow ) how we recover from failure. Failure recovery can be defined by specific controls
within failure policies that allow us to recover by resetting state or instantiating new components to take over the operation
