on what database?

it really support only AS400 and Oracle

other - trigger based and (my personal opinion) ugly - https://community.talend.com/t5/Design-and-Development/MySQL-CDC-Capture-understanding-logic/td-p/95086

I have few processes using 3rd party tools as producer CDC to Kafka, and than Talend as Kafka consumer for parse changes

what You want to implement?

Hi @harithareddy051,

As @xdshi says above, the CDC components are only available in the subscription (commercial, paid for) editions of Talend, not the free version you have installed.

Chris

Hi,

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.

Regards,

Chris

Hello,

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)---->

Let us know if it is OK with you.
