steven zhang commented on KYLIN-904:
------------------------------------
You are right scan recursively is necessary to local file system
i think ResourceStore have a abstract method named collectResource
FileResourceStore and HBaseResourceStore have implementation respectively one
scan recursively another scan plain in the future
> Recursive queries to method collectResourceRecursively(ResourceStore.java) is
> not necessary

> URL: https://issues.apache.org/jira/browse/KYLIN-904
> Project: Kylin
> Issue Type: Improvement
> Affects Versions: 0.7.1
> Reporter: steven zhang
> Priority: Minor
> Labels: github-import
> Fix For: 0.7.1
>
>
> it is not necessary collect Resource Recursively when kylin load metadata to
> cache
> because the path of Resource in table kylin_metadata such as /cube ,
> /cube_desc etc. is not prefix structure as follow example
> /a/b
> /a/b/xx
> /a/b/xx/xx
> /a/b/yy/yy
> /a/c
> even it have the prefix structure also it is unnecessary
> for example it will get all the records with prefix ‘a/b’ when query ‘a/b’
> /a/b
> /a/b/xx
> /a/b/xx/xx
> /a/b/yy/yy
> when query ’/a/b/xx‘ it will return children of it
> /a/b/xx/xx (it already queried before)
> so it is not necessary to query path of resource recursively
