pipeTo(WriteStream<com.datastax.oss.driver.api.core.cql.Row> dst)
Same as
ReadStream.pipeTo(WriteStream, Handler) but returns a Future of the asynchronous result |

pipeTo(WriteStream<com.datastax.oss.driver.api.core.cql.Row> dst,
Handler<AsyncResult<Void>> handler)
Pipe this
ReadStream to the WriteStream. |

While it's paused, no data will be sent to the data handler.

ReadStreamReadStream to the WriteStream.
Elements emitted by this stream will be written to the write stream until this stream ends or fails.
Once this stream has ended or failed, the write stream will be ended and the handler will be
called with the result.
