In this section, we will examine how transducers are implemented. We will also get a basic idea of how our own transducible source of data can be implemented.
Some transducers can internally use state. It turns out that the existing reference types, such as atoms and refs, aren't fast enough for the implementation of transducers. To circumvent this problem, transducers also introduce a new volatile reference type. A volatile reference represents a mutable variable that will not be copied into the thread-local cache. Also, volatile references are not atomic. They are implemented in Java using the
volatile keyword with a
