Java is a widely used programming language that can handle large amounts of data easily. In the field of data technology, data processing is necessary, and big data and real-time data processing technology are hot topics now.

In Java, there are libraries and frameworks available for processing big data and real-time data. This article will introduce some commonly used Java big data streaming and real-time data processing technologies.

1. Java technology for processing big data streams

Big data stream processing refers to processing unlimited, high-speed data streams. These data streams usually enter the system at high speed and must be processed immediately. deal with. In Java, there are many techniques for handling big data streams.

1. Apache Kafka

Apache Kafka is a distributed data streaming platform that can handle millions of messages per second and is highly scalable, reliable and fault-tolerant. Kafka can publish data streams to multiple subscribers, and can also process data streams as streaming processing. Kafka can be integrated through Java libraries, and Java applications can publish and consume Kafka messages.

2. Apache Flink

Apache Flink is a distributed stream processing framework that can handle limited and unlimited data streams. Flink is high-performance, scalable, and flexible, and can handle a variety of data processing methods, including batch and stream processing. Flink can be written and integrated in Java, and it also provides many runtime optimizations for Java applications, such as Java serialization and JVM tuning.

3. Apache Spark

Apache Spark is a distributed computing framework for big data processing, which can process data in batch or stream processing. Spark provides advanced tools for fast data processing, such as Spark Streaming, which can use stream processing when processing data. Spark can also be integrated into Java applications, giving Java applications access to Spark functionality.

2. Java technology for processing real-time data

Different from big data stream processing, real-time data processing refers to processing data immediately after it enters the system. In Java, there are many techniques available for processing real-time data.

1. Hazelcast Jet

Hazelcast Jet is an open source framework for stream processing and distributed computing. Jet can process millions of events per second in milliseconds, with extremely high throughput and low latency. Jet can be written and integrated using Java and processes data without storing it on disk.

2. Apache Storm

Apache Storm is an open source framework for distributed real-time stream processing that can handle high-speed, continuous data streams. Storm is scalable, highly available, fault-tolerant, and supports Java, Python, and other programming languages. Storm allows real-time computation and visualization while processing data.

3. Redis

Redis is a high-performance data storage system that uses memory as a storage medium and can process requests and responses in milliseconds. Redis can be used as a message broker and publish-subscribe system, and supports Java libraries for access and integration. Redis can also be used for tasks such as caching and ranking.

Conclusion

In this article, we introduced some common Java technologies for processing big data streams and real-time data. Each of these technologies can be considered an important tool for processing big data and real-time data, with different advantages and different applicable scenarios. To extend the data processing capabilities of your Java applications, you can choose the Java data technology that's right for you.
