Plugin record no dateUpdated and uid
This might not be the answer you were looking for, but I don't think you need to go to great lengths trying to achieve something that in my opinion is not necessary. While it might seem to be not &quot;clean&quot; to have database table columns that are not required by your application/plugin, consider that todays ICT infrastructure is powerful enough to not slow down due to a few additional columns in a database and its tables.
I would even consider it more risky trying to alter the &quot;base&quot; of Craft or the Yii framework than to live with a few autogenerated columns.
If you are very sensitive to performance and have many database requests, you might not want to use active record since its higher level of abstraction can come with a performance penalty in certain situations.
