org.pentaho.di.trans.streaming.common.FixedTimeStreamWindow<I>

所有已实现的接口:

StreamWindow<I,org.pentaho.di.core.Result>

public class FixedTimeStreamWindow<I extends List>
extends Object
implements StreamWindow<I,org.pentaho.di.core.Result>

A StreamWindow implementation which buffers rows of I by a fixed amount of time and size, executing each batch in a subtransformation.

方法详细资料

buffer

public Iterable<org.pentaho.di.core.Result> buffer(io.reactivex.Flowable<I> flowable)

从接口复制的说明: StreamWindow

Takes an iterable (would typically be a StreamSource.flowable()} call) and buffers it according to the window strategy. Returns an iterable of data for the window. Depending on stream implementation, the output could also be transformed. For example, the FixedTimeStreamWindow will pass windowed data to a subtransformation, and return the transformed results.
