> HIVE-21857 introduced an optimization for ordering predicates inside a filter based on a cost function. After HIVE-23456, this optimization can run only if the the digest normalization (introduced in CALCITE-2450) in CBO is disabled (via {{calcite.enable.rexnode.digest.normalize}}).
> The goal of this issue is to decouple the sort predicate optimization from digest normalization. After the changes here the optimization shouldn't be affected by the value of {{calcite.enable.rexnode.digest.normalize}} property.
