[Bug] Restored deleted items are not appearing in dbt Snapshots 1.9

[paritoshg2010]

Is this a new bug in dbt-core?

• I believe this is a new bug in dbt-core
• I have searched the existing issues, and I could not find an existing issue for this bug

Current Behavior

In dbt-core 1.9, with dbt snapshot new feature to capture the new records for the deleted items, I have noticed that if the deleted records are restored, those are not reinserted in snapshot table.

snapshot config:

strategy='check',

hard_deletes= 'new_record'

As you see in the attached screenshot, the deleted record entry is the last entry in this table.

Expected Behavior

Once the records are restored, the deleted entry (is_deleted='True') in snapshot table should be invalidated and the new record will be created.

Steps To Reproduce

1. Run dbt snapshot on any table, to replicate all the records from monitored table.
2. Now delete one record from monitored table & run the dbt snapshot on that table. There will be new entry created for the deleted record with the previous one getting invalidated and the new one with dbt_is_deleted='True'.
3. Now again try to restore that delete record in the monitored table, and run the dbt snapshot on it. The new entry for the restored item is not getting create in snapshot table.
