Return a list of all reservations by subnet ID - #313 for Cassandra back-end (if possible)
This is a follow-on request from GL #313 (closed) - which was not implemented for Cassandra database back-end due to the technical challenges, described as:
In #313 (closed), the idea about paging is to reduce the communication:
- with SQL database you can ask a page of the whole result from the DB: the kea-server will translate this page to JSON and sends to the requestor.
- with Cassandra you do not have this so you can get the whole result and page it in the kea-sever, etc.
To summarise, what matters is where the paging is done. In #313 (closed) we decided to do it only in the DB (so only for SQL DBs).
This ticket is to explore what we could to meet the use-case need (similarly or differently) with the Cassandra back-end
