[Discuss] Enhance Bitwise Function

Hi everybody,

 

I'd like to kick off a discussion on enhancing bitwise functions in calcite.
Bitwise functions are non-standard operator, but most of DBs have implemented. So I made some comparisons with some major DBs to discuss what kind of  bitwise functions need to be supported in calcite. I built an umbrella jira[1] for this. And the comparison details are in the attachment.

 

Would love to hear your thoughts, thanks.

 

Best,
Hailong wang.
