        Deprecated.
        Use DRedReteBackendFactory instead of setting this option to true.
        The incremental query evaluator backend can evaluate recursive patterns. However, by default, instance models that contain cycles are not supported with recursive queries and can lead to incorrect query results. Enabling Delete And Rederive (DRED) mode guarantees that recursive query evaluation leads to correct results in these cases as well.

        As DRED may diminish the performance of incremental maintenance, it is not enabled by default.

      • expandWeakenedAlternativeConstraints

        public static final QueryHintOption<java.lang.Boolean> expandWeakenedAlternativeConstraints
        This hint allows the query planner to take advantage of "weakened alternative" suggestions of the meta context. For instance, enumerable unary type constraints may be substituted with a simple type filtering where sufficient.
