I am using Java couchbase sdk in my application. While setting up the DefaultCouchbaseEnvironment, I came across the property RetryStrategy. Now I am using the default configuration for which the retry strategy is BestEffortRetryStrategy. According to documentation
BestEffortRetryStrategy will retry the operation until it either succeeds or the maximum request lifetime is reached
By default the maximum request lifetime is 75 seconds.
Now what i what i want to understand here is what does retry mean here. Does retry mean retrying the request whenever an exception occurs or does it mean it will retry to allocate this request to some node to process the request in case it can't and it will keep retrying for 75 seconds?
I am looking at my application logs for different exceptions to understand this and I could see that TemporaryFailureException wasn't retried and i could also see that in some instances RequestCancelledException was being thrown after 75 seconds. Is it fair to assume that couchbase retries a request to assign it to node to process it and not actually retries on any exception once it makes it to the node that will process this request?
