    Difference Between Clojure, Kotlin and Scala
    JVM language comparison: Clojure, Kotlin and Scala The JVM ecosystem has multiple powerful programming languages, each with unique features and programming paradigms. Clojure, Kotlin, and Scala are three popular choices in JVM environments. This article will focus on comparing the differences in JVM and JDK integration between these three languages. Clojure Clojure is a dynamic functional programming language inspired by Lisp. It emphasizes immutability, concurrency and simplicity. JVM: Generate bytecode that can be run on the JVM. Can call Java classes and methods, making it ideal for integrating Java libraries, but not well integrated with Java frameworks,

  • Methods for Combining INSERT and UPDATE in PostgreSQL for Efficient Data Management
    Methods for Combining INSERT and UPDATE in PostgreSQL for Efficient Data Management
    Efficient PostgreSQL data management: clever combination of Insert and Update operation When using relational databases such as postgreSQL, it is often necessary to perform new records or update existing records based on whether the record exists. This demand is very common in the scenario of data synchronization, import operation, or frequent data updates. Without the correct use of UPSERT technology, data redundancy, integrity problem or application code logic may be complicated. 1. UPSERT understanding "UPSERT" is a combination of "Update" and "INSERT". It describes a database operation: if the record does not exist, new lines are inserted, and the existing row is updated if the record exists.

  • Hybrid Cache Strategy in Spring Boot: A Guide to Redisson and Caffeine Integration
    Hybrid Cache Strategy in Spring Boot: A Guide to Redisson and Caffeine Integration
    Hybrid cache in Spring Boot application In modern application development, performance and scalability are the key factor that determines the success or failure of the system. By reducing database loads, reducing delays, and ensuring seamless user experience, it plays a key role in improving these aspects. However, no single cache solution can perfectly adapt to all scenes. Local cache (such as Caffeine) can provide extremely fast speed because it runs in memory and close to the application. They are very suitable for reducing the response time of frequent access to data. On the other hand, a distributed cache (such as using Redisson) provides scalability and consistency between multiple instances of the application. Distributed
