In my example, I have a pre/post after an update in my CDF. Is there a way to determine by an external_id per each microbatch, which columns have changed?
| external_id | subscribe_status | subscribe_dt | end_sub_dt | _change_type | _commit_version | _commit_timestamp |
|---|---|---|---|---|---|---|
