This change fixes an issue we have faced during some time in our stack. |
|
Displaying non-current columns is intentional in Glue, as users may use LakeFormation and need to access dropped columns. Users should not rely on Glue for the latest table status, Iceberg metadata should always be considered the source of truth. |

(Reopen #11334)
Closes #7584
This PR addresses a feature request for improving the Glue Schema generation process. It introduces a new configuration option that allows users to exclude non-current fields from the Glue Schema, providing clarity and reducing confusion for Athena users who primarily query current data.
In PR #3888, the Glue schema generation was modified to include all historical fields. This was intended to help users recognize previously used columns and avoid duplicating column names. However, in practice, this approach has led to confusion among users (for example, the same issue explained in #7584 ).
The current behaviour remains unchanged.
