Filtering Streams


The java.util.streams.Stream interface was introduced in Java 8. It emits elements and supports a variety of operations that perform computations based on these elements. A stream can be finite or infinite, slow or fast emitting. Naturally, there is always a concern that the rate of the newly emitted elements may be higher than the rate of the processing. Besides, the ability to keep up with the input reflects the application's performance. The Stream implementations address the backpressure (when the rate of the element processing is lower than their emitting rate) by adjusting the emitting and processing rates using a buffer and various other techniques. In addition, it is always helpful if an application developer makes sure that the decision about processing or skipping each particular element is made as early as possible so that the processing resources are not wasted. Depending on the situation, different operations can be used for filtering the data.
