Hi,
Batch API are traditionally used for larger amounts of data while Rest APIs are used for smaller, live chunks of data. To reduce traffic on Batch APIs, please consider exposing the lastUpdated field and adding an optional filter.
For example, on CurrentPupils, which is the one I am concerned about initially, if you expose the lastUpdated field for that table then the user could request only records that have been updated since a specific time. this would reduce the page size and make it easier for client side data to be updated. if no filter was supplied, then it would just revert to a return all api call.
Regards,
Leon
