Class ProcessingTime

java.lang.Object

org.apache.spark.sql.ProcessingTime

All Implemented Interfaces:

java.io.Serializable, Trigger, scala.Equals, scala.Product

public class ProcessingTime
extends java.lang.Object
implements Trigger, scala.Product, scala.Serializable

:: Experimental :: A trigger that runs a query periodically based on the processing time. If interval is 0, the query will run as fast as possible.

Scala Example:

   df.write.trigger(ProcessingTime("10 seconds"))

   import scala.concurrent.duration._
   df.write.trigger(ProcessingTime(10.seconds))
 

Java Example:

   df.write.trigger(ProcessingTime.create("10 seconds"))

   import java.util.concurrent.TimeUnit
   df.write.trigger(ProcessingTime.create(10, TimeUnit.SECONDS))
