  1. How to use it

Retrying on failure

Livebox can retry the request when an error occurs during the execution of fetcher instance. There are two strategies that can be used:

  • Interval, using .retry(RetryStrategy.INTERVAL), this retries the request 3 times with a 1 second interval between each try.

  • Exponencial backoff, this is a known strategy that works very well when dealing with network errors. Exponencial backoff uses the formula f(x)=bxf(x) = b^xf(x)=bxto calculate the delay with a 1 second interval between each try, for a max of 3 times.
