Kea Configuration Backend (CB or config backend) gives Kea servers the ability
to manage and fetch their configuration from one or more databases. In
this documentation, the term "Configuration Backend" may also refer to
the particular Kea module providing support to manage and fetch the
configuration information from the particular database type. For
example, the MySQL Configuration Backend is the logic implemented within
:ischooklib:`libdhcp_mysql.so`, which provides a complete set of functions to
manage and fetch the configuration information from the MySQL database.
The PostgreSQL Configuration Backend is the logic implemented within
:ischooklib:`libdhcp_pgsql.so`, which provides a complete set of functions to
manage and fetch the configuration information from the PostgreSQL database.
From here on, the term "database" is used to refer to either a MySQL or
PostgreSQL database.

To use a MySQL configuration backend, :ischooklib:`libdhcp_mysql.so` must
be compiled and the DHCP servers must be configured to load it. It is compiled
when the ``-D mysql=enabled`` configuration switch is used during the Kea build.
