Large input xml request to BPEL

Question

Does BPEL load the whole input request xml in memory?
I have a input request having multiple IDs. The oracle business rule transforms 1 id at a time.
BPEL calls the business rule in flowN for a size of 20. (processes 20 ids at a time)
The input request size is huge more than 150K ids at a time. Does BPEL load the whole input xml in memory ( DOM tree)?
what is a better way to do it

Answer 1

Avoid calling the BPEL process with big payload.
It loads everything into memory, you could use debatching technique in the file adapter to split the payload into more manageable sizes.
Do stress testing to check whether its working fine under different loads.
