We are using the below API and Reltio seems to be ignoring the "partSize" parameter. Why?
The customer was using export V2. In this version of the export, the "skipPostprocessing" will default to true when it is not specified in the physical tenant. If "skipPostprocessing" is set to true, then part size is ignored.
We can change the physical storage to be set to export V2 and skipPostprocess to be set to false. However, please be aware that export V2 is "smart export" processing. Therefore, it is still possible that partsize could be ignored - please refer to https://docs.reltio.com/exportapi/exportdataintomultiplefiles.html.
