+# 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.
+
+# This line starts database initialization to 1.0.

+# 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.
