Query- Live data Replication - Approach

Hi Team,

I have two queries with respect to live data replication. Please share the better approach to achieve the same.

Case 1. Source: RDS to Destination:Snowflake via Matillion.

Case 2. Source: On-Prem Oracle to Destination: Snowflake via Matillion (Without using any Query component as it will put more load in Oracle server)

Thanks in advance!!!

Matillion has a CDC Feature which supports Oracle as a Source for AWS hosted snowflake instances.

Check out the documentation here for an overview and how to configure

We managed to configure CDC with Matillion and its working for record INSERT/UPDATE but unfortunately DELETE records in Oracle are not propagated through Matillion to Snowflake. Please advice on this.

Thanks in advance!!!!

Thanks for writing in on the DELETE issue, though we’ve not seen that problem before. Community posts like this one don’t accept attachments; can you please forward your server log to You can download the log from the Admin menu to the upper-right of the canvas.

I expect there are clues to this behavior contained in that file. Also, please let us know if you’re seeing any other error message related to this issue.

Best Regards,

Dear Dave,

Please let me know how to proceed if i want to propagate only INSERT/UPDATE events in source Oracle RDS excluding DELETE action into Snowflake while performing CDC job.

Hi Learning At Thirty,

As per your question in thread 23525, it’s not possible to selectively exclude certain DML operations in Matillion CDC.

Best regards,
