> kylin uses class org.apache.kylin.common.persistence.ResourceTool to do
> metadata download, upload, remove, etc. The algorithm for resource
> transversal is not very effective. For instance, for an "execute_output" with
> key "/execute_output/\{uuid}", the algorithm will try to check whether it's a
> folder with sub-resources, this makes un-necessary time cost, and in cases of
> metadata with lots of jobs, it may last for a long time before the finish.
