Paging

Functionality for sending a large list of information as smaller 'pages' containing a subset of the list elements.

This functionality requires that the list can be sorted according to a relevant attribute, so that pages can be calculated in a predictable manor by defining max and min attributes in a page. 

The following operations uses paging:

• Checksums: The sort order here is checksum calculation checksum.
• FileIDs: The sort order here is file change timestamp.
• Audit trails: The sort order is sequence number.
