Need to remove unused fields from Record type.

hi,romav0001  Unused fields in a database don't directly cause performance issues since you wouldn't be writing or reading from that field we might have to think regarding efficiency in the long run. May vote for option C. That both the record type and the database schema remain synchronized. This approach eliminates the unused field from the record type and also in the database table and also has consistency in both the record and db.

Hello romav0001 

The correct option is A. Delete the field from the record type and optionally delete the column from the database table.
To remove an unused field from a data-synced record type, delete the field directly from the record type. Optionally, you can also delete the corresponding column from the database table for better database hygiene.

still confused for this question anyone can answer this ???

What is confusing you here? You could take two approaches to answering the question:

1. using your knowledge of records and databases determine which is the correct answer
2. using your knowledge of records/CDTs eliminate the answers that are incorrect to find the correct answer

Using a combination of 1. and 2. should lead you to the correct answer.

If you don't know why the answer is A. at all then ask specific questions here and folk can try and help you understand.

thanks Stewart Burchell I was just confused between option A and B I just wanted to know the best practice I can implement 

Can anyone confirm which answer will be correct option A or option C as Data sync is enabled so in that case if I delete the column from Database and perform full resync of the record type then also record type will be updated right? 

its option A
