[jira] [Updated] (ARROW-5636) [C++][Gandiva] Expression cache should not use ToString on data type

     [ https://issues.apache.org/jira/browse/ARROW-5636?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Pindikura Ravindra updated ARROW-5636:
--------------------------------------
    Component/s: C++ - Gandiva

> [C++][Gandiva] Expression cache should not use ToString on data type
> --------------------------------------------------------------------
>
>                 Key: ARROW-5636
>                 URL: https://issues.apache.org/jira/browse/ARROW-5636
>             Project: Apache Arrow
>          Issue Type: Bug
>          Components: C++ - Gandiva
>            Reporter: Pindikura Ravindra
>            Priority: Major
>
> The expression cache in gandiva generates uses the ToString() method of arrow::DataType() for both hashing and equality.
> This is error-prone - we should have a visitor for generating hash, and use the equality visitor for comparison.
