best choice for today's load of 100TB-level data workloads. The spark team also retains multiple documents documenting how spark ETL is responsible for the operations of petabytes of production workloads. Spark is a fast, scalable, and flexible open source distributed computing platform that is compatible with Hadoop and Mesos and supports multi-stream computing modes, including streaming, graphics-centric operations, SQL Access plus distributed machine learning. Spark's real-world expansion re

Find the element that only appears once.Ideas:The first thing to think about is the use of sorting, which makes it easy to find non-repeating elements after sorting.Later on there is a more ingenious solution, that is, to use XOR to

Each Flink program relies on a set of Flink libraries. The Flink itself consists of a set of classes and dependencies that are required to run. The combination of all classes and dependencies forms the core of the Flink runtime and must exist when a Flink program runs. These core classes and dependencies are packaged into flink-dist. jars. In order to avoid excessive dependencies and classes in Classpath by default, the Flink core dependency does not contain any connectors or libraries

HA scenario, HA container monitors the activity of the primary server and then converts the information into HA events to be handled by Streambase Monitor. Monitor is to get data from System container and HA container and process it. Streambase that the HA problem should be handled by CEP, meaning that if there is a problem with the component, it will certainly be reflected in the output stream of system container and HA container, and then Monitor h

trying to challenge this conclusion, interested comrades please see for yourself. On the other hand, people have doubts about the traditional CEP solution, and think that its non distributed architecture is not scalable enough to scaleout to meet the massive data processing requirements. This time, Yahoo! S4 and Twitter storm just scratched people's itch. 2. Scalability More specifically, it is the ability to scaleout. The so-called scale out (http
