Method Detail

builder

public static <T> LoadBalancerCommand.Builder<T> builder()

submit

public rx.Observable<T> submit(ServerOperation<T> operation)

Create an Observable that once subscribed execute network call asynchronously with a server chosen by load balancer. If there are any errors that are indicated as retriable by the RetryHandler, they will be consumed internally by the function and will not be observed by the Observer subscribed to the returned Observable. If number of retries has exceeds the maximal allowed, a final error will be emitted by the returned Observable. Otherwise, the first successful result during execution and retries will be emitted.
