 ## 混合云云上节点做缓存
 
 在混合云 ML 场景，为保证数据安全性和一致性，通常会将训练数据保存在私有云，公有云上的计算节点通过专线或公网访问私有云上的数据。这种跨云数据读写方式会导致较高的读写延时和较大的带宽开销，同时训练耗时更长也会导致算力资源浪费。可通过 CubeFS 的本地缓存及分布式缓存机制，将训练数据缓存到公有云节点，减少数据的跨云数据传输，从而提升训练迭代效率。

-
-如果训练任务的数据集存储路径固定，可通过预热的方式，将训练数据提前加载到多副本子系统。

-``` bash
-./cfs-preload -c config.json

-配置文件中各参数的含义如下表所示：

 In hybrid cloud ML scenarios, to ensure data security and consistency, training data is usually stored in private cloud, and the computing nodes in public cloud access the data on the private cloud through dedicated lines or public networks. Such cross-cloud data reading and writing approach is prone to high latency and large bandwidth overhead, while longer training time can also lead to wasted computational resources. By using CubeFS's local and distributed cache mechanisms, training data can be cached on public cloud nodes, reducing cross-cloud data transmission and improving training iteration efficiency.
