Subject [jira] Created: (HIVE-914) Speed up UDFJson
Date Thu, 05 Nov 2009 21:05:32 GMT
Speed up UDFJson

                 Key: HIVE-914
                 URL: https://issues.apache.org/jira/browse/HIVE-914
             Project: Hadoop Hive
          Issue Type: Improvement
            Reporter: Paul Yang
            Assignee: Paul Yang

In UDFJson, a new JSONObject is created for each call to evaluate(). Since it is likely that
evalue() will be called with multiple paths for a given JSON string, a performance improvement
can be realized by caching the JSONObject created from a JSON string.
