[GitHub] [incubator-uniffle] advancedxy commented on issue #407: [FEATURE] Cache index files on the server side

advancedxy commented on issue #407:

   Do you observe any performance issue for this case?
   
   If the index file is only accessed few times(say 1,2 times), there's no need to cache this file. And normally, the linux system will have file cache to speed up file access.
   
   If the shuffle server is indeed influenced by this problem, I believe we may need an IndexFileAccessManager to trigger the index file caching and manage eviction.
