Subject [jira] Commented: (HADOOP-6532) Path objects are heavy
Date Tue, 02 Feb 2010 20:22:20 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-6532?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12828756#action_12828756
] 

Doug Cutting commented on HADOOP-6532:
--------------------------------------

Another alternative might be to have Path, like String, contain only a char[].  Then it would
have the same weight as String, but still be a distinct type with its own methods, constructors,
etc.

> Compared with java.lang.String, org.apache.hadoop.fs.Path is much heavier since it contains
URI.  The size of a Path is roughly 3 times of a String.  See some numbers in the comments.
> A major impact of decreasing Path size is allowing ls, archive, etc. on directories with
many files.
