. The spark streaming is therefore suitable for applications where historical data and real-time data can be combined for analysis. Of course, the real-time requirements are not particularly high applications can also be fully competent. In addition, the data reuse mechanism of RDD can get more efficient fault-tolerant processing.This chapter summarizes:The 1.Spark streaming itself is like an application on the spark core that processes the data internally by invoking the Spark Core's RDD interf
having to swipe each time.Here we also add an inner class Viewholder,convertview to create the Viewholder object when it is empty, and store the instance of the control in Viewholder. The Settag method is then called to store the Viewholder object in the view, and the Viewholder is taken out using Gettag when not empty. It is not necessary to use the Findviewbyid () method to get the instance every time after the instance of the control is cached.Both of these steps have been optimized to impro

Remove the {dede:arclist flag= ' F ' row= ' 5′} and {/dede:arclist} and change [field:arcurl/] to the address you want to jump to [field:litpic/] Change to the address of the picture you want to display on the slide, and change [Field:title function= ' Html2text (@me)
