[jira] [Created] (CALCITE-3732) Implement bit functions and operators

hailong wang created CALCITE-3732:
-------------------------------------

             Summary: Implement bit functions and operators
                 Key: CALCITE-3732
                 URL: https://issues.apache.org/jira/browse/CALCITE-3732
             Project: Calcite
          Issue Type: Improvement
          Components: core
    Affects Versions: 1.21.0
            Reporter: hailong wang
             Fix For: 1.22.0


Bit function is non-standard operators, but all db has implemented, such as mysql, postgresql.

Calcite has implemented BIT_AND, BIT_OR in https://issues.apache.org/jira/browse/CALCITE-2770, BIT_XOR in https://issues.apache.org/jira/browse/CALCITE-3591. BIT_COUNT is in progress https://issues.apache.org/jira/browse/CALCITE-3697, BIT_NOT(~) is in progress https://issues.apache.org/jira/browse/CALCITE-3592.

So I think we should also implement Bitwise AND(&), Right shift(>>), Left shift(<<), Bitwise XOR(^), Bitwise OR(|). And data types support tinyint, smallint, int, bigint like before.
