All Implemented Interfaces:

EndpointStrategy

public final class StickyEndpointStrategy
extends AbstractEndpointStrategy

An EndpointStrategy that will always return the same endpoint once it's picked until the endpoint is no longer valid, then it'll pick another one. If multiple threads calling the pick()} method at the same time, it's possible that they get different result if there was no endpoint being picked yet or the previously picked endpoint is no longer value. The pick will be eventually settled to the same one.
