Abstract In some important flink data processing scenarios, it is necessary to implement Exactly Once data processing. Exactly Once means that when flink processes data, it can ensure that data is not lost and data is not repeated. The entire flink processing link is roughly divided into three links: Source -> Transform -> Sink. Selecting […]

Teach you step by step how to implement the producer-consumer model
?Yin’s Blog | Yin’s Blog (yinkai.cc), welcome to my blog to read. This article will introduce you to the definition, characteristics, and processes of the producer-consumer model, and take you step by step to implement the producer-consumer model. 1. Introduction The producer-consumer pattern is a concurrency design pattern used to solve the collaboration and data […]

kafka: partitioning strategy for producers to send messages
In order to increase the scalability of the system, Kafka introduces the concept of partitioning. The partitioning mechanism in Kafka refers to dividing each topic into multiple partitions (Partitions), and each partition is an ordered set of message logs. Each message under a topic will only be saved in a certain partition, and will not […]
Implementing the producer-consumer pattern using Python multi-threading
What is the producer consumer pattern In the process of software development, we often encounter such scenarios: Some modules are responsible for producing data, which are processed by other modules (the modules here may be: functions, threads, processes, etc.). The module that generates data is called a producer, and the module that processes data is […]
Kafka Producer message sending process and mechanism
Kafka Producer message sending process and mechanism Message sending process We can use the Producer class provided by Kafka to quickly send messages. The sending demo code is as follows: public class MyProducer {<!– –> // Server connection address private static final String BOOTSTRAP_SERVERS =”worker1:9092,worker2:9092,worker3:9092″; //Basic TOPIC private static final String TOPIC = “disTopic”; public […]

What are some ways to implement the producer-consumer pattern in concurrent programming?
Java all-round learning + interview guide: https://javaxiaobear.cn We mainly learn how to use wait/notify/Condition/BlockingQueue to implement the producer-consumer pattern. Producer-consumer model Let’s first take a look at what the producer-consumer pattern is. The producer-consumer pattern is a very common design pattern in programming and is widely used in scenarios such as decoupling and message queues. […]
