>             Project: Apache Arrow
>          Issue Type: Bug
>          Components: C++ - Gandiva
>    Affects Versions: 7.0.0
>         Environment: Aliyun ECS
> CentOS Linux release 7.9.2009 (Core)

> I use Gandiva JNI  and function greater_than_or_equal_to is not support.
> Is it really not support or i use it in a wrong way?
