关于柔性负载均衡应用场景

目前dubbo提供了非常多的负载均衡策略，每种算法都有优劣，想了解下目前柔性负载均衡算法是否具备生产可用的能力，目前是否有企业使用该负载均衡策略呢？
另外看到柔性算法中的因子很多，到底什么样的场景适合使用该策略呢？

The issue names Dubbo's flexible load-balancing strategy but does not identify a file, test, or entry point. First clarify which implementation and production-use evidence are in scope, then review the existing load-balancing documentation and strategy details; done would require a documented explanation of suitable scenarios and production readiness.
