=== Database Configuration

The configuration for this component lies in the `standalone.xml`, `standalone-ha.xml`, or `domain.xml` file
in your distribution.  The location of this file
depends on your <<fake/../../operating-mode.adoc#_operating-mode, operating mode>>.

            <property name="dataSource" value="java:jboss/datasources/KeycloakDS"/>

Possible configuration options are:

dataSource::
  JNDI name of the dataSource

jta::
  boolean property to specify if datasource is JTA capable

driverDialect::
  Value of database dialect.
  In most cases you don't need to specify this property as dialect will be autodetected by Hibernate.

initializeEmpty::
  Initialize database if empty. If set to false the database has to be manually initialized. If you want to manually initialize the database set migrationStrategy to `manual` which will create a file with SQL commands to initialize the database. Defaults to true.

migrationStrategy::
  Strategy to use to migrate database. Valid values are `update`, `manual` and `validate`. Update will automatically migrate the database schema. Manual will export the required changes to a file with SQL commands that you can manually execute on the database. Validate will simply check if the database is up-to-date.

migrationExport::
  Path for where to write manual database initialization/migration file.

showSql::
  Specify whether Hibernate should show all SQL commands in the console (false by default).  This is very verbose!

formatSql::
  Specify whether Hibernate should format SQL commands (true by default)

globalStatsInterval::
  Will log global statistics from Hibernate about executed DB queries and other things.
  Statistics are always reported to server log at specified interval (in seconds) and are cleared after each report.

schema::
  Specify the database schema to use
