Subject [jira] [Commented] (HIVE-4044) Add URL type
Date Wed, 27 Feb 2013 23:07:13 GMT

    [ https://issues.apache.org/jira/browse/HIVE-4044?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13588887#comment-13588887

Samuel Yuan commented on HIVE-4044:
-----------------------------------

You're right, the idea is that it will enable better encoding of URLs. Kevin found that breaking
up the URL into its components and storing them as separate columns results in significant
space savings. The original plan was to implement this idea with RCFile, but with the new
ORC file format I decided to wait for that instead, and to submit this part separately.

However, it looks like the improvements of the ORC file have erased any gains we would have
gotten by breaking up URLs into the individual components, so this won't be needed any more.

> Having a separate type for URLs would enable improvements in storage efficiency based
on breaking up a URL into its components. The new type will be named "URL" and made a non-reserved
keyword (see HIVE-701).
