Load Limits for loading journal lines via the erpintegrations REST API ImportBulkData

Hi Guys

I am specifically interested in the limits for loading journal lines via the erpintegrations REST API ImportBulkData Operation which uses the FBDI process under the hood:

Any thoughts as to the maximum number of journal lines that can be loaded per batch? per hour? per day? Using the REST API.

Also can any settings be changed on fusion for a specific subscription to permit the volume limit to be increased?

Thank you!
