	$database->beginBatch();
	// all INSERT, UPDATE, DELETE query append into batch query stack for execution after applyBatch
	$uuid = $database->query('SELECT uuid() as "uuid" FROM system.schema_keyspaces LIMIT 1;')[0]['uuid'];
	$database->query(
			'INSERT INTO "users" ("id", "name", "email") VALUES (:id, :name, :email);',
			[
				'id' => $uuid,
				'name' => 'Mark',
				'email' => '[email protected]'
			]
		);

	$database->query(
			'DELETE FROM "users" WHERE "email" = :email;',
