public class QueryHintsResolver extends QueryHintsRelShuttle
Note: duplicate query hints are not checked here.
For KV hints such as state ttl hints and lookup join hints, they will be merged. If the keys with same hint name conflict, only the first value is chosen.
For LIST hints such as regular join hints, they will all be retained.
