Hi Sonali, this feature already exists – you can use a couple of different log events that we create to track this. For your use case, it sounds like alter_table may be best. 

You might also be interested in events related to the schema change – these events allow to track these changes along with other important information like who has initiated that change: 

- change_schema_config (when action is taken via UI) 

- change_schema_config_via_api 

- change_schema_config_via_sync (when config is updated during the sync) 

I'd encourage you to check out our logs documentation for more detail!
