Drop Topic prefix

In this example each record has an incoming topic name prefixed with solr-. Assuming that our topic is solr-customer the following example will strip the prefix of solr- allowing us to write to the collection named customer. This is accomplished by using the RegexRouter transformation that is bundled with Apache Kafka.
