We have observed that the custom connector extracts the change log data of each case individually through separate API calls (not affected by pagination). However, when working with the OOTB connector, we observed that the sys_audit records were accessed by compiling multiple cases into a single API call depending on the batch size defined.

Has anyone had any experience with this before and does it affect the source system performance? We have concerns that we might hit the default rate limit in ServiceNow as we are planning to extract a large volume of data.
