| 6 | * Retry several times with a fixed delay to wait after the last execution | |
| 7 | * failure until the maximum attempts is reached. | |
| 8 | * | |
| 9 | * If delay is 500ms and max retries is 5, it means that a retry will be | |
| 10 | * attempted every 500ms until 5 attempts are reached (inclusive). For example, | |
| 11 | * you want to connect to an external system at t1=0 and the connection timeout | |
| 12 | * (100ms) is triggered at t2=100ms. Using this retry will provide the following | |
| 13 | * behavior: | |
| 14 | * | |
| 15 | * <ul> | |
| 16 | * <li>0: connect</li> | |
| 17 | * <li>100: timeout</li> | |
| 18 | * <li>600: connect</li> | |
| 19 | * <li>700: timeout</li> | |
| 20 | * <li>1200: connect</li> | |
| 21 | * <li>1300: timeout</li> | |
| 22 | * <li>1800: connect</li> | |
| 23 | * <li>1900: timeout</li> | |
| 24 | * <li>2400: connect</li> | |
