Goal

Background:

Minor modifications in USC_Map configuration are resulting into significant increase in memory usage for the realtime processing pipeline. After our latest modifications, Pipeline allocates significantly more memory (greater than 100% increase), resulting in memory allocation errors.

Currently there are ~3000 lines configured in IFW_USC_MAP. We have modified 5 of them and after these modifications Realtime Pipeline loading stops at the USC_DATA_Module.

Questions:

  1. Can you please provide us with summary of known limitations and recommendations for IFW_USC_MAP configuration regarding pipeline memory usage (i.e. best practice recommendation)?
  2. Can you please provide benchmarks / guidelines for estimating memory usage based on IFW_USC_MAP complexity and/or number of records in configuration?
  3. Can you please provide more detailed documentation regarding the OptimizeFor parameter for DAT_USC_Map pipeline module?
