Detailed Description

A single host update.

This DTO is a tuple describing a change of the state of a host reservation table. Depending on the type, it either adds a missing entry or removes an entry that shouldn't exist anymore. Using a list of updates can be used in various ways:

the current state of a host reservation table (describing the difference to an empty table)
the difference between to table (what changes have to be made to make one table identical to the other)

◆ incremental_update_id

size_t ahri::AdminDBClient::HostUpdate::incremental_update_id {0}

An incremental update identifier.

Host updates are stored in the backend using an incremental update identifier, which is always incrementing. Using the update identifier of all DHCP servers, a cleanup procedure can determine which host updates can be removed from AdminDB to save space and reduce the table length. The hightest update identifier of each incremental update batch shall be registered somewhere, such a cleanup procedure can read from to determine the lowest common processed update identifier of all DHCP servers.

For host updates retrieved using fetch_all_host_reservations(), the update identifier shall have the default value to indicate that the host information isn't part of an incremental update. All such host updates must have the type set to ADD.
