hmmmm can't find how to set retries in apollo3? 🤔

How would you like this to work? Apollo Android 3 uses coroutines so you can use

Flow.retry{}

with Flow or a simple while loop for suspend functions

I did find various result regarding flow.retry examples... but with suspend not so much. Im also wondering if I should have used flows instead of suspends... I really mostly went with that since it was what I found in a working example I based myself off of. Like with a loop id have to manually check if the request went thru, set delays before retry, etc where as with flow id be able to set it all up using parameters, unless im mistaking? Its been a minute since I did android and I just started up again, and coroutines were not a huge thing back when

It all depends your strategy too. For a simple strategy, you could do something like this:

private suspend fun <D: Query.Data> ApolloClient.executeWithRetries(
      query: Query<D>,
      maxRetries: Int,
      delayMillis: Long
  ): ApolloResponse<D> {
    var retries = 0
    while (retries < maxRetries) {
      try {
        return query(query)
      } catch (e: Exception) {
        delay(delayMillis)
        retries++
      }
    }
    throw Exception("max retries reached")
  }

fair enough

We could add stuff like that in Apollo but we can't really make any assumption about what retry strategy is required

I mean, couldn’t you add something like

abstract class RetryStrategy

providing some common implementations (linear, exponential, etc)? This would provide some common strategies, but while allowing us to define our own.

What I'm wondering is how much of this is docs vs actual implementations. For the

Flow

case, I'm pretty sure there are implementations out there. For the

suspend

case, it's a bit of boilerplate but maybe there are extensions to do this somewhere.
