TextSocketSource

class TextSocketSource extends Source with Logging

A source that reads text lines through a TCP socket, designed only for tutorials and debugging. This source will *not* work in production applications due to multiple reasons, including no support for fault recovery and keeping all of the text read in memory forever.
