    • sortBySymbolTable

      public static boolean sortBySymbolTable
    • groupedRedirectionThreshold

      public static int groupedRedirectionThreshold
      If we have more than this many entries per group, instead of creating a large flat row redirection, we create a row redirection that is composed of the group indices and an accumulated cardinality cache. This can save a significant amount of memory when the groups are large and storing them using our RowSet structure is more efficient.
