Big data is a series of processing methods for massive data storage, calculation, statistics, analysis and so on. The amount of data processed is TB-level, or even PB or EB-level data, which can not be completed by traditional data processing methods. Big data involves distributed computing, high concurrency processing, high availability processing, clustering, real-time computing and so on. Big data brings together the most popular and popular IT technology of IT. Big data is the infrastructure of cutting-edge areas such as machine learning, deep learning and AI.

Big data technology provides the basis for decision-making, plays an important role in the decision-making of government, enterprises, and scientific research projects, and plays an important role in social governance and enterprise management. For example, China, the United States, the European Union and other countries have included big data in their national development strategies, and large enterprises such as Microsoft, Google, Baidu and Amazon have also listed big data technology as a key bargaining chip for future development.

So, what are the commonly used big data techniques?

The first stage JavaSE + MySql + Linux

Java basic → OOP programming → Java Collection → IO/NIO → Eclipse → Intellij IDEA → Socket Network Technology → Mysql Database → JDBC Api → JVM memory structure → phase project actual combat → Linux (VMware, CentOS, directory structure, Linux command)

The second stage Hadoop and ecosystem

Hadoop → MapReduce → Hive → Avro and Protobuf → Zookeeper → HBase → phoenix Redis → Flume distributed → SSM (Spring, SpringMVC, Mybatis) → Kafka architecture

The third stage Storm and Spark and their biosphere

Scala → Spark Job → Spark RDD → spark job deployment and Resource allocation → Spark shuffle → Spark SQL → Spark Streaming → Spark ML → azkaban

Other in stage IV

Python and data Analysis

The fifth phase of the project is the comprehensive application of actual combat and technology.

Big data needs to master the technology in the commercial actual combat stage: the actual operation enterprise big data deals with the business scene, analyzes the demand, the solution implementation, and the comprehensive technology actual combat application.

Under the premise of having the foundation of Java programming language, we can learn the above big data technology. Big data is the direction of development in the future, challenging our analytical ability and cognitive style of the world. Therefore, we keep pace with the times, meet the changes, and continue to grow, and master big data's core technology.
