> 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.
