Hi Keerthana,
The table below accurately describes the current limits:
Please note that the 10 GB limit for remote files is only applicable when you enable row consolidation.
For POST /entities, the request body size limit is 50 MB. This is a platform-level limit for any HTTP POST request body in Reltio, so it applies to the Post Entity API as well. If you exceed it, Reltio returns HTTP 413 Payload Too Large.

Subject: Confirmation of Data Loader CSV, JSON, and API POST Size Limits
Could you please confirm the maximum upload limits in Data Loader-for CSV files (is it 33 GB or 10 GB?), the maximum supported size for JSON files, and the maximum payload size allowed for API POST requests?
