[jira] [Created] (ARROW-5701) [C++][Gandiva] Build expressions only for the required selection vector types

Pindikura Ravindra created ARROW-5701:
-----------------------------------------

             Summary: [C++][Gandiva] Build expressions only for the required selection vector types
                 Key: ARROW-5701
                 URL: https://issues.apache.org/jira/browse/ARROW-5701
             Project: Apache Arrow
          Issue Type: Task
          Components: C++ - Gandiva
            Reporter: Pindikura Ravindra
            Assignee: Pindikura Ravindra


We currently build the JIT for all known selection vector types (there are 4 supported types). For very long expressions, this increases the build time by 4x.

 

Instead, we should build only for the required selection vector type.
