Supported implementations:

wrr : Weighted round robin (Kratos Client 内置默认算法)
p2c : Power of two choices
random : Random

@dandyhuang Would you describe some of your scenarios where you need a consistent hashing LB policy. This will give us a better understanding of the background and the motivation for implementing it.

@clement2026 You can understand it as distributing some of the user's redis data and cache to different machines.
