Article Introduction：How to renew the Redis distributed lock? The correct posture of the Redis distributed lock. According to Fei Chao, when many students use distributed locks, they directly search on Baidu to find a Redis distributed lock tool class and use it directly. The key is this tool The class is also filled with many System.out.println(); and other statements. In fact, the more correct approach to Redis distributed lock is to use the client tool redisson. For specific introduction, you can search the largest gay dating website github. How to answer first if you If you used Redis' distributed locks correctly before and read the corresponding official documents, this problem is easy. Let's take a look at it. Frankly speaking, if your English is great, then read the English documents.

Article Introduction：Overview of distributed locks In a multi-threaded environment, in order to ensure that a code block can only be accessed by one thread at the same time, in Java we can generally use synchronized syntax and ReetrantLock to ensure that this is actually a local lock method. But now companies are adopting distributed architecture. In a distributed environment, how to ensure that threads on different nodes execute simultaneously? Therefore, distributed locks are introduced, which are a way to control mutually exclusive access to shared resources between distributed systems. In a distributed system, multiple services are deployed on multiple machines. When a user on the client initiates a data insertion request, if there is no distributed lock mechanism guarantee, then multiple services on the multiple machines may perform concurrently.

Article Introduction：Redis is a fast and reliable in-memory database that is widely used in distributed systems. In distributed systems, transaction processing is a key challenge. This article will introduce how Redis achieves the reliability of distributed transactions and provide some specific code examples. Redis implements distributed transactions through four commands: MULTI, EXEC, DISCARD and WATCH. The MULTI command is used to start a transaction, the EXEC command is used to execute all commands in the transaction, and the DISCARD command

Article Introduction：With the rapid development of Internet services, issues such as high concurrency and multi-computer room deployment have become increasingly complex. In this context, distributed lock and distributed transaction technology are becoming more and more important. Distributed locks are a mechanism used to coordinate access to shared resources by multiple processes in a distributed system. In a stand-alone environment, mutex locks can be used to achieve synchronization, but in a distributed environment, multiple processes may be distributed on different servers, and mutex locks can only lock one process and cannot coordinate synchronization across machines. Distributed locks are designed to solve this problem

Article Introduction：With the development of Internet technology, distributed systems have become an important topic, and distributed locks are also one of the important technologies. In a distributed system, the order and security of access to shared resources by multiple processes or threads can be guaranteed by using distributed locks. In Java, there are many solutions to implement distributed locks, among which the Redis distributed lock solution is one of the more commonly used methods. Redis is a high-performance, persistent, in-memory database with good data structure support and distributed characteristics. Redis cluster

Article Introduction：Preface First of all, what exactly is a distributed transaction? For example, when we execute a business logic, we have two steps to operate the A data source and the B data source respectively. When we perform data changes in the A data source, when we execute the data in the B data source If a runtime exception occurs, then we must roll back the operation of data source B and roll back the operation of data source A; this situation often occurs in payment business; for example, if the ticket purchase business fails to pay at the end, then the previous All operations must be rolled back. If the previous operations are distributed in multiple data sources, then this is a typical distributed transaction rollback; understand what distributed transactions are, then the solution for distributed transactions in Java is JTA (i.e. JavaTransactionAPI); springboo
