Performance: in-memory cache is used instead of pageable

Hi,

I have a dataflow which contains a nested schema (XML extraction)

When I execute the job I see in the log that in-memory cache is used because there is a nested schema. The problem is that after few minutes the memory gets to 99% usage (23.2GB out of 24GP) and the process is very slow.

Is there a way to improve the performance?

Thanks,

Amir
