@Deprecated
public class ClickHousePipedStream
extends ClickHousePipedOutputStream

Deprecated.

will be removed in v0.3.3, please use ClickHouseDataStreamFactory.getInstance().createPipedStream() instead

A combination of PipedOutputStream and PipedInputStream for streaming data between server and client. To avoid dead lock and high memory usage, please make sure writer and reader are on two separate threads.
