The best solution to address the timeouts and eliminate the impact of long-running reporting queries without disrupting order processing is:A
Reporting queries will point to read replica. Application will still point to primary db for write / read operations.
The correct answer to this question is A: Create a read replica. Move reporting queries to the read replica. This solution is designed to alleviate the load on the primary database used by the ordering application. By offloading the reporting queries to a read replica, the primary instance is freed up to handle operational transactions like order processing without contention from the resource-intensive reporting queries. This should effectively reduce or eliminate the timeouts currently experienced during order processing.
