With the monitoring data, we can define our own alarm rules in the monitoring framework, and call the Aliyun container service-provided triggers to enlarge or shrink the container when the indicator alarm occurs. The following is a influxdb,kapacitor to introduce how to implement a custom elastic scaling with a trigger and a

In the Android development of the ListView, ScrollView used very high frequency, but a good application we can see that the effect is not so rigid, Android native ListView and ScrollView can not meet this requirement, Therefore, this flexible view is needed for development. In peacetime development, I collected the top and bottom pull with elastic listview and ScrollView, here to share to everyone, there is a need to use can be downloaded directly.Ela

Elastic Job learning and elasticjob Learning From the execution result, the results of the slice are different as the server increases. When there is only one server, all the parts are uploaded to this server. When the number of servers is increased to two, the partition result is 0 1 2 3 4 and 5 6 7 8 9. When the number of servers is increased to three, the results are 0 1 2 9, 3 4 5, and 6 7 8, respectively. In addition, we also found t

The operation and maintenance cost of cluster is mainly from the third party real-time application hosting, the different applications have different dependencies on the system environment, such as: Spark streaming is developed using Python, it needs a lot of librari

Elastic distribution Data Set RddThe RDD (resilient distributed Dataset) is the most basic abstraction of spark and is an abstraction of distributed memory, implementing an abstract implementation of distributed datasets in a way that operates local collections. The RDD is the core of Spark, which represents a collection of data that has been partitioned, immutable, and can be manipulated in parallel, with different data set formats corresponding to d
