Wrap the given SourceSource with a SourceSource that will restart it when it fails or complete using an exponential backoff.

Error handling




This FlowFlow will never emit a complete or failure, since the completion or failure of the wrapped SourceSource is always handled by restarting it. The wrapped SourceSource can however be cancelled by cancelling this SourceSource. When that happens, the wrapped SourceSource, if currently running will be cancelled, and it will not be restarted. This can be triggered simply by the downstream cancelling, or externally by introducing a KillSwitchKillSwitch right after this SourceSource in the graph.

This uses the same exponential backoff algorithm as BackoffBackoff.

Reactive Streams semantics

emits when the wrapped source emits

completes when the wrapped source completes
