Hello Sucharita Das,

I went through your blog which talks about incremental data load with Change Tracking. In the blog its only implemented for one table. I am trying to modify the query for multiple tables but facing some issues, how can we modify this to implement for multiple tables.

Thanks,

Gauri Pawse

Some minor changes are required to handle multiple tables. I will try to write an article on this.

Hi Sucharita Das,

It will be good to understand how the same pipeline can be configured to handle incremental load for multiple tables using change tracking.

Thanks!

Can you explain for Multiple tables

Hi,

As far as I've understood, this solution requires enabling change tracking in SOURCE Database. Right?

If so, unfortunately it is in most scenarios not applicable and therefore this pattern will be useless. In serious environments one can just forget modifying ERP (or any other heavy OLTP Datasource) tables and set the change tracking on. In such cases, the classical anchor based incremental loading pattern is still the best way.

Thanks for the information anyway.
