TextSocketContinuousStream

class TextSocketContinuousStream extends ContinuousStream with Logging

A ContinuousStream that reads text lines through a TCP socket, designed only for tutorials and debugging. This ContinuousStream will *not* work in production applications due to multiple reasons, including no support for fault recovery.

The driver maintains a socket connection to the host-port, keeps the received messages in buckets and serves the messages to the executors via a RPC endpoint.
