Class RetryingAsyncOperation<T>

java.lang.Object

io.picodata.driver.api.retry.RetryingAsyncOperation<T>

All Implemented Interfaces:

Runnable

public class RetryingAsyncOperation<T>
extends Object
implements Runnable

Wrapper to run operation in an asynchronous way with retries. Operation can be run many times but the final result will be stored in a result future.

Each operation attempt is limited with a timeout returned by RequestRetryPolicy.getRequestTimeout(). See TarantoolRequestRetryPolicies.InfiniteRetryPolicy for an implementation example.
