 Note that by default, the operation will be retried an infinite number of times and the transaction will never time out. It is therefore recommended that the client choose a default transaction retry limit or timeout value that is suitable for their application. This can be set either at the transaction level using the ``set_retry_limit`` or ``set_timeout`` transaction options or at the database level with the ``set_transaction_retry_limit`` or ``set_transaction_timeout`` database options. For example, one can set a one minute timeout on each transaction and a default retry limit of 100 by calling::
 
     db.options.set_transaction_timeout(60000)  # 60,000 ms = 1 minute
-    db.options.set_retry_limit(100)
