  +== Example: Basic configuration
   
  -To route change event records to topics based on their content, configure the content-based routing transformation in the Kafka Connect configuration for the {prodname} connector.
  -Configuration of the content-based routing SMT requires you to specify a regular expression to define routing criteria. 
  +To configure a {prodname} connector to route change event records based on the event content, you configure the `ContentBasedRouter` SMT in the Kafka Connect configuration for the connector.
   
  -For example, you might add the following configuration to your connector configuration:
  +Configuration of the content-based routing SMT requires you to specify a regular expression that defines the filtering criteria. 
  +In the configuration, you create a regular expression that defines routing criteria. 
  +The expression defines a pattern for evaluating event records.
  +It also specifies the name of a destination topic where events that match the pattern are routed. 
  +The pattern that you specify might designate an event type, such as a table insert, update, or delete operation.
  +You might also define a pattern that matches a value in a specific column or row.
  +
  +For example, to reroute all update (`u`) records to an `updates` topic, you might add the following configuration to your connector configuration:

  The preceding example specifies the use of the `Groovy` expression language.
  The regular expression reroutes all update (`u`) records to the `updates` topic, and routes other records to the default topic.

  {prodname} binds certain variables into the evaluation context for the SMT.
