 * Main database structure configuration file.
 *
 * Here are described all the tables, fields and indexes Friendica needs to work.
 * The entry order is mostly alphabetic - with the exception of tables that are used in foreign keys.
 *
 * Syntax (braces indicate optionale values):
 * "<table name>" => [
 *	"comment" => "Description of the table",
 *	"fields" => [
 *		"<field name>" => [
 *			"type" => "<field type>{(<field size>)} <unsigned>",
 *			"not null" => 0|1,
 *			{"extra" => "auto_increment",}
 *			{"default" => "<default value>",}
 *			{"default" => NULL_DATE,} (for datetime fields)
 *			{"primary" => "1",}
 *			{"foreign|relation" => ["<foreign key table name>" => "<foreign key field name>"],}
 *			"comment" => "Description of the fields"
 *		],
 *		...
 *	],
 *	"indexes" => [
 *		"PRIMARY" => ["<primary key field name>", ...],
 *		"<index name>" => [{"UNIQUE",} "<field name>{(<key size>)}", ...]
 *		...
 *	],
 * ],
 *
 * Whenever possible prefer "foreign" before "relation" with the foreign keys.
 * "foreign" adds true foreign keys on the database level, while "relation" is just an indicator of a table relation without any consequences
 *
 * If you need to make any change, make sure to increment the DB_UPDATE_VERSION constant value below.
