Information in this document applies to any platform.

Goal

The customer is running a complex query which contains 32 segments . The customer is observing that the memory footprint of the nqserver is huge and that results in the server crash.

Analyzing the logs it appears in some of the subqueries, they are combining data from 2 different sources,

a. Oracle Data Warehouse and
b. Marketing OLTP

Then BI server would have to execute the subquery and generate IN list causing the memory footprint to increase.

Is there a possibility of the write back feature to handle these kind of queries?
