--------------------------------------
[~hailong wang], Is this still in progress? Is anything ready to be reviewed to go into release 1.27?
> Implement bit functions and operators
> -------------------------------------
>
> Key: CALCITE-3732
> URL: https://issues.apache.org/jira/browse/CALCITE-3732
> Project: Calcite
> Issue Type: Task
> Components: core
> Affects Versions: 1.21.0
> Reporter: hailong wang
> Assignee: hailong wang
> Priority: Major
>
> Bit function is non-standard operators, but all db has implemented, such as mysql, postgresql.
> Calcite has implemented BIT_AND, BIT_OR in CALCITE-2770, BIT_XOR in CALCITE-3591. BIT_COUNT is in progress CALCITE-3697, BIT_NOT(~) is in progress 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.
