protectedvirtual

Inserts or deletes a single host.

All information is available here. Calls db::CqlExchange::executeMutation().

Parameters

insert	insert or delete a host
host	Host object from which options are retrieved and inserted/deleted into/from the Cassandra database
subnet_id	identifier of the subnet to which the host belongs
reservation	reservation for the current denormalized table entry
option_space	option space for the current denormalized table entry's option
option_descriptor	option descriptor containing information for the current denormalized table entry's option

protectedvirtual

Merge denormalized table entries that belong to the same host into a single host, one by one.

Parameters

target_host	host which can contain multiple reservations and options to which other distinct reservations and options are added.
source_host	host that is being search for new reservations and options that will be merged into the old host.
