When I'm reading the API of spark streaming, I'm confused by the 3 different durations
StreamingContext(conf: SparkConf <http://spark.apache.org/docs/latest/api/scala/org/apache/spark/SparkConf.html> , batchDuration: Duration <http://spark.apache.org/docs/latest/api/scala/org/apache/spark/streaming/Duration.html> ) DStream window(windowDuration: Duration <http://spark.apache.org/docs/latest/api/scala/org/apache/spark/streaming/Duration.html> , slideDuration: Duration <http://spark.apache.org/docs/latest/api/scala/org/apache/spark/streaming/Duration.html> ): DStream <http://spark.apache.org/docs/latest/api/scala/org/apache/spark/streaming/dstream/DStream.html> [T] Can anyone please explain these 3 different durations Best, Siyuan
