When I'm trying to see change data feed changes by applying alter table set delta.enableChangeDataFeed = true. Property was enabled but i couldn't see any changes.
I'm getting error like there are no changes
I have set Property is true but i couldn't see any changes
When you switch Change Data Feed on, the changes are collected only from the next version after you did the change. If you will try to call table_changes using earlier version, then it will generate an error.
It's described in the docs, in the section marked as "Important!":
Only changes made after you enable the change data feed are recorded; past changes to a table are not captured.
