Course Introduction:Many programmers who have worked for many years still have a very basic understanding of databases. They are confused as soon as they go out for interviews. They don’t understand basic SQL statements, more complex SQL queries, and SQL statement optimization. They don’t even know how to use them. Redis improves system performance and can withstand tens of millions of concurrencies. This set of courses will help you thoroughly understand MySQL locks, execution plans, indexes, MVCC & Redis transactions, cache, breakdown, penetration, avalanche, warm-up, etc., and you can complete all database interviews in one set!

Course Introduction:Data consistency capability: Which is better, MySQL or TiDB? Introduction: Data consistency has always been one of the core issues of distributed databases. In actual application scenarios, it is very important for distributed databases to ensure data consistency. This article will focus on comparing the data consistency capabilities of MySQL and TiDB, and demonstrate their specific implementation methods through code examples. 1. MySQL’s data consistency capability MySQL is a relational database. Its common data consistency mechanisms include

Course Introduction:Data consistency between Redis and the database can be achieved through the following mechanisms: 1. Master-slave replication mechanism, which achieves consistency through asynchronous replication; 2. Double-write mechanism, which writes data to Redis and the database simultaneously to maintain synchronization; 3. Optimistic locking , control concurrent access through version numbers or timestamps to ensure consistency; 4. Transaction compensation mechanism, perform compensation operations to restore consistency when data is inconsistent. Choosing the appropriate mechanism based on the application scenario and tolerance can ensure the consistency of Redis and the database.

Course Introduction:The Redis database solves data consistency problems through the following mechanisms: Master-slave replication: The master server synchronously replicates write operations to the slave server. Redis Sentinel: Monitors the Redis server and performs failover and failure recovery to maintain database availability and data consistency. Redis Cluster: Use consistent hashing algorithm to shard data to different nodes. Transaction: Perform write operations in atomic operations, ensuring either all success or all failure. Redis Modules: Provide consistency guarantees. For example, Redis Raft uses a consensus algorithm to ensure data consistency. Other measures: optimize data models, use cache to buffer write operations, regular backup and recovery.

Course Introduction:How to solve the data collection consistency problem in C++ big data development? Introduction: In C++ big data development, data collection is an important link. However, due to large amounts of data and scattered data sources, data consistency problems may be encountered during the data collection process. This article will introduce the definition and common solutions of data consistency problems, and provide a C++ code example to help readers better understand how to solve data consistency problems. 1. Definition of data consistency problem: In big data development, data consistency problem refers to
