I'm not aware of any free solutions for CDC, as this type of thing can be very complex, and is generally considered an enterprise level requirement. Any company developing a solution will naturally expect to get paid for their work.
If it's something you need to do in the free version of Talend, then there are approaches which may well work, but you'll need to engage with a paid consultant to discuss your requirements and develop a solution which works for you. This is unlikely to be something that can be done quickly.
In the long run, you'll probably be better off looking at commercial options like the Talend subscriptions, and if it's something you need to do urgently, then you're definitely going to have to pay for it.
With talend open source, you have to compare tables to get the changed data.
The work flow looks like:
The target DB----------------->tMap(inner join and set "Catch lookup inner join reject" as true)-->output(changed data)
The source DB(lookup)---->
