| backOffRandomizationFactor | N | Randomization factor, between 1 and 0, including 0 but not 1. Randomized interval = RetryInterval * (1 ± backOffRandomizationFactor). Defaults to `"0.5"`. | `"0.5"` |
| backOffMultiplier | N | Backoff multiplier for the policy. Increments the interval by multiplying it with the multiplier. Defaults to `"1.5"` | `"1.5"` |
| backOffMaxElapsedTime | N | After MaxElapsedTime the ExponentialBackOff returns Stop. There are two valid formats, one is the fraction with a unit suffix format, and the other is the pure digital format that will be processed as milliseconds. Valid time units are "ns", "us" (or "µs"), "ms", "s", "m", "h". Defaults to `"15m"` | `"15m"` |

| maxLen | N | The maximum number of messages of a queue. If both `maxLen` and `maxLenBytes` are set then both will apply; whichever limit is hit first will be enforced. Defaults to no limit | `"1000"` |
| maxLenBytes | N | Maximum length in bytes of a queue. If both `maxLen` and `maxLenBytes` are set then both will apply; whichever limit is hit first will be enforced. Defaults to no limit. | `"1048576"` |
