TraceFeignClientAutoConfiguration overrides default Feign builder with this:
static Feign.Builder builder(BeanFactory beanFactory) {
return Feign.builder().retryer(Retryer.NEVER_RETRY).client(client(beanFactory));
}
Why is retryer set to NEVER_RETRY? Can I use a custom retryer with Sleuth? Can I use a custom builder (i.e. io.github.resilience4j.feign.Resilience4jFeign.Builder) with Sleuth?
