ZERO DownTime Deployment of application with frequent database DDL change

Hi I am trying to deploy my application with zero downtime. My app is quite frequent with database ddl changes. What are all the possible ways to achieve it with zero transaction failure in the app. Though we can use kubernetes to achieve zero downtime of the application, I don't want any failures in service request happening at the time of deployment due to database change like dropping the columns, dropping the table and changing the datatype
