the only options, the rest don't help to solve the HTTP 429 error

I am going with CE. By combining response code handling and controlled exponential backoff with truncation, the microservice can gracefully manage the 429 error, communicate effectively with the client, and avoid overwhelming the server.

A. Implement subsequent retry with the same interval window. C. Consecutive retries should truncate exponential backup. HTTP 429 "Too Many Requests" response status code indicates that the user has sent too many requests in a given amount of time ("rate limiting"). In response to this, the developer can implement subsequent retries with the same interval window, which means the code should try to resend the request after a specific period of time. The developer can also use an approach known as "exponential backoff", where the delay between subsequent retries increases exponentially, rather than linearly, to give the server more room to recover. However, to prevent the delay from becoming too large, the exponential increase should be truncated at a certain point, which is what is meant by "consecutive retries should truncate exponential backup".

The developer should implement subsequent retry with the same interval window (A) and return errors in the response code (E) to manage the HTTP 429 "Too Many Requests" status code in the microservices code. This will ensure that the request is retried with a proper wait time and the error is properly communicated to the user.
