| max\_retries    | int      | 6           | The maximum number of attempts to make when calling the API before giving up.<br />It defines how many times the client will retry the API call if it fails.<br />Default value is 6, indicating the client will attempt the API call up to 6 times in total                                                                                                                                                                                                                                                                                                        |
| retry\_interval | int      | 10          | The interval in seconds between consecutive retry attempts.<br />This is the waiting period before the client tries to call the API again after a failed attempt.<br />Default value is 10 seconds, meaning the client waits for 10 seconds between retries.                                                                                                                                                                                                                                                                                                        |
| max\_wait\_time | int      | 360         | The maximum total time in seconds that the client will spend on all retry attempts before giving up.<br />This sets an upper limit on the cumulative waiting time for all retry attempts.<br />If this time is exceeded, the client will stop retrying and raise an exception.<br />Default value is 360 seconds, meaning the client will cease retrying if the total time<br />spent on retries exceeds 360 seconds.<br />The client throws a ReadTimeout error after 60 seconds of inactivity. If you want to<br />catch these errors, use max\_wait\_time >> 60. |
