Conventions used

There are a number of text conventions used throughout this book.

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: “So, the KStream bean is created as an instance of KStream<String,String>.”

A block of code is set as follows:
public interface Transformer<K, V, R> {
    void init(ProcessorContext var1);
    R transform(K var1, V var2);
    void close();
}

Any command-line input or output is written as follows:

bin/connect-standalone.sh config/connect-standalone.properties connect-riskcalc-mongodb-sink.properties

Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “Here, click the Build a Database button to create a new database instance.”
