In a blog series, I describe how to make use of an Active/Active (read only) SAP HANA database in SAP S/4HANA on premise.
The idea is to free up resources on the primary SAP HANA database by routing expensive analytical requests to a secondary SAP HANA database, which many customers operate anyway as part of their high availability strategy.
You find the parts of the blog series here:
Part 1: Introduction
Part 2: Architecture overview
Part 3: The client decides
Part 4: SAP HANA database hints
Part 5: Where was my data read from?
