Thanks for review, @twalthr . I also think that it would be best if calcite could support << and >>, however I am not sure whether calcite could support this very well for two reason, one is that it looks bitwise shift operation is not sql standard and from [HIVE-9859](https://issues.apache.org/jira/browse/HIVE-9859) discussion it looks that ">>" has potential conflicts with nested complex type declaration in hive which also uses calcite. So maybe there are two ways: 1. As you said make calcite suport this. 2. Since [Spark](https://spark.apache.org/docs/2.3.0/api/sql/index.html#shiftleft) and [Hive](https://cwiki.apache.org/confluence/display/Hive/LanguageManual+UDF) both have shiftleft and shiftright, maybe we could also add this named as shiftleft and shiftright...
