             Summary: PrepareStatement cache issue when there are new segments built
                 Key: KYLIN-3536
                 URL: https://issues.apache.org/jira/browse/KYLIN-3536
             Project: Kylin
          Issue Type: Bug
          Components: Query Engine
            Reporter: Ma Gang
            Assignee: Ma Gang


PrepareStatement cache will have issue when there are new segments built, because the OLAPContext is cached with preparedStatement, and the choosed Realization is cached in the OLAPContext, so if there are new segments built after cache, the new segments will not be used for the query. The fix is always use the latest Realization Instance in the OLAPContext.
