On production environment I am using spring.jpa.hibernate.ddl-auto=validate but I found new columns are added in my production DB automatically.
I have done a small POC with dummy application it is not adding a column on my local system.
Can anyone help me understand what could be the issue with spring.jpa.hibernate.ddl-auto=validate property.
Any help is appreciated.
PFA I visited the documentation but did not get enough details:
