Class PassingTimeStrategy

java.lang.Object

org.apache.servicecomb.core.invocation.timeout.PassingTimeStrategy

All Implemented Interfaces:

InvocationTimeoutStrategy

@Component
public class PassingTimeStrategy
extends Object
implements InvocationTimeoutStrategy

 based on time synchronization
 any time to calculate timeout: now - start time of invocation chain

 consumer: c
 producer: p
