I strongly agree with Jorn and Russell. There are different solutions for data movement depending upon your needs frequency, bi-directional drivers. workflow, handling duplicate records. This is a space is known as " Change Data Capture - CDC" for short. If you need more information, I would be happy to chat with you. I built some products in this space that extensively used connection pooling over ODBC/JDBC.
Happy to chat if you need more information. -Sachin Naik >>Hard to tell.
