C_CPI Integration Suite Development Practice Question
You are designing an integration flow that must transform a large XML payload using a mapping step, and you observe that the flow runs out of memory under production load. Which approach best addresses the memory issue while preserving the transformation logic?
⚠ Common exam trap
The trap here is assuming that more memory or a different scripting language solves a large-payload problem, when the actual fix is changing the processing model from whole-payload to streaming or chunked.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable streaming in the mapping step or use the XML to CSV converter with streaming, and process the payload in chunks
Large XML transformations can exhaust memory when the entire payload is materialized at once. Streaming-based processing, such as the XML to CSV converter or streaming-capable mapping, handles the payload incrementally, keeping only a small portion in memory at any time. Increasing heap size, loading into a script string, or duplicating into a property all fail to address the root cause.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Enable streaming in the mapping step or use the XML to CSV converter with streaming, and process the payload in chunks
Why this is correct
Streaming-based transformation processes the payload incrementally rather than loading it entirely into memory. Using streaming-aware steps such as the XML to CSV converter or enabling streaming in supported mapping contexts reduces the memory footprint and allows large payloads to be handled without exhausting the heap.
- ✗
Add a Content Modifier step before the mapping to copy the payload into a property
Why it's wrong here
Copying the payload into an exchange property duplicates the data in memory, effectively doubling the footprint. This step does not reduce memory usage and would make the out-of-memory problem worse, not better. Content Modifier is not a memory optimization tool.
- ✗
Increase the tenant's heap size by contacting SAP support
Why it's wrong here
Tenant heap size is managed by SAP and is not a customer-configurable parameter. Relying on support to raise it is not a viable design solution, and even if possible, it would not scale as payloads grow. The correct approach is to change how the payload is processed, not to request more memory.
- ✗
Replace the mapping step with a Groovy script that loads the entire payload into a string
Why it's wrong here
Loading the entire payload into a string in a Groovy script increases memory consumption rather than reducing it, because the full content is held in memory. This approach would worsen the out-of-memory condition and is not a valid optimization for large XML payloads.
