Hello,

Creating this feature request on behalf of the customer.

The customer has requested that HVR’s AdaptDDL functionality enable Alter on Redshift cluster.Redshift currently supports such ALTER operations under certain conditions, HVR always performs a drop and recreate when a column length is changed.

This behaviour introduces significant risk of data loss and latency, especially for large tables, and is inconsistent with what the customer observes when manually running the same ALTER in Redshift (which succeeds without issue).

The customer is using AdaptDDL with OnEnrollBreak=WARNING, and expects non-destructive behaviour. They have also validated that Redshift permits these operations using the same user as HVR.

Please check if this is feasible and consider it for implementation if viable.

Affected account tier – Platinum
