Determined to figure out the timings of spring retry template exponential back off policy.
For example, the defaults are the following for the policy:
- The default 'initialInterval' value - 100 millisecs.
- The default maximum backoff time (30 seconds).
- The default 'multiplier' value - value 2 (100% increase per backoff).
- Simple retry policy of 5 attempts
| Retry | Seconds | Timestamp |
|---|---|---|
| 1 | 0.1 | 8:40:47 PM:408 |
| 2 | 0.3 | 8:40:47 PM:508 |
| 3 | 0.7 | 8:40:47 PM:708 |
| 4 | 1.5 | 8:40:48 PM:108 |
| 5 | 3.1 | 8:40:48 PM:908 |
The goal was to give a general idea of how long the max retry process will take without guessing.
