[jira] [Created] (ARROW-17351) [C++][Compute] Support to initialize expression with a string

LinGeLin created ARROW-17351:
--------------------------------

             Summary: [C++][Compute] Support to initialize expression with a string
                 Key: ARROW-17351
                 URL: https://issues.apache.org/jira/browse/ARROW-17351
             Project: Apache Arrow
          Issue Type: Improvement
          Components: C++
    Affects Versions: 8.0.1
            Reporter: LinGeLin


I want to achieve such a function, first would like to ask you which way to achieve better

 

For example, I want to initialize an expression whose content is

a210 - (a210 /203) * 203 = 0

This means that column A210 modulo 203 is equal to 0

 

How do you compare these two ideas?

 

"(subtract(a210, multiply(divide(a210, 203), 203)) == 0)" to Expression

or

"a210-(a210/203)*203==0" to Expression
