# This is the Kea schema specification for MySQL.
|
|
#
|
|
# The schema is reasonably portable (with the exception of the engine
|
|
# specification, which is MySQL-specific). Minor changes might be needed for
|
|
# other databases.
|
|
|
|
# To create the schema, either type the command:
|
|
#
|
|
# mysql -u <user> -p <password> <database> < dhcpdb_create.mysql
|
|
#
|
|
# ... at the command prompt, or log in to the MySQL database and at the 'mysql>'
|
|
# prompt, issue the command:
|
|
#
|
|
# source dhcpdb_create.mysql
|
|
#
|
|
# This script is also called from kea-admin, see kea-admin db-init mysql
|
|
#
|
|
# Over time, Kea database schema will evolve. Each version is marked with
|
|
# major.minor version. This file is organized sequentially, i.e. database
|
|
# is initialized to 1.0, then upgraded to 2.0 etc. This may be somewhat
|
|
# sub-optimal, but it ensues consistency with upgrade scripts. (It is much
|
|
# easier to maintain init and upgrade scripts if they look the same).
|
|
# Since initialization is done only once, it's performance is not an issue.

|
|
#
|
|
# Indexes
|
|
# =======
|
|
# It is likely that additional indexes will be needed. However, the
|
|
# increase in lookup performance from these will come at the expense
|
|
# of a decrease in performance during insert operations due to the need
|
|
# to update the indexes. For this reason, the need for additional indexes
|
|
# will be determined by experiment during performance tests.
|
|
#
|
|
# The most likely additional indexes will cover the following columns:
|
|
#
|
|
# hwaddr and client_id
|
|
# For lease stability: if a client requests a new lease, try to find an
|
|
# existing or recently expired lease for it so that it can keep using the
|
|
# same IP address.
|
|
#
|
|
# Field Sizes
|
|
# ===========
|
|
# If any of the VARxxx field sizes are altered, the lengths in the MySQL
|
|
# backend source file (mysql_lease_mgr.cc) must be correspondingly changed.
|
|
#
|
|
# Portability
|
|
# ===========
|
|
# The 'ENGINE = INNODB' on some tables is not portable to another database
|
|
# and will need to be removed.
|
|
#
|
|
# Some columns contain binary data so are stored as VARBINARY instead of
|
|
# VARCHAR. This may be non-portable between databases: in this case, the
|
|
# definition should be changed to VARCHAR.
