- What are the smart caching mechanisms?
- There are seven common intelligent caching mechanisms: "page cache", "database cache", "object level cache", "query result cache", "CDN cache", "eviction strategy" and "elimination strategy": 1. Page caching, which caches dynamically generated page content; 2. Database caching, which stores frequently accessed data in the cache to reduce the number of database queries; 3. Object-level caching, which caches frequently used objects or data in memory to improve the reading and writing speed; 4. Query result caching, caching the results of database queries, etc.

- What is the programmer caching mechanism?
- Programmer caching mechanism refers to a technical means of using caching in software development to improve system performance and response speed. Common programmer caching mechanisms include: 1. Database caching: caching database query results into memory to reduce the number of accesses to the database; 2. Page caching: caching dynamically generated pages or page fragments into memory or disk to Reduce server-side calculations and network transmission; 3. Object caching: cache frequently used objects or data structures into memory to reduce creation and initialization overhead; 4. CDN caching, etc.

- What are the database caching mechanisms?
- Database caching mechanisms include memory cache, database page cache, database query cache, database connection pool, read-write separation, sharding, full-text search engine, etc. Detailed introduction: 1. Memory cache is a caching mechanism that stores data in the database in memory. Memory cache has high-speed read and write performance, which can greatly improve the performance and response speed of the database; 2. Database page cache is a cache mechanism that stores data in the database. The data page is stored in the cache mechanism in the memory. The data page is the basic unit of storing data in the database and usually contains multiple records; 3. Database query caching, etc.

- What are the data caching mechanisms?
- Data caching mechanisms include memory cache, database cache, file cache, distributed cache, local cache, message queue cache, compression cache, LRU, LFU and FIFO, etc. Detailed introduction: 1. Memory cache is one of the most common forms of data caching. It stores data in the computer's RAM for faster access and use. The advantage of memory cache is fast access, but the disadvantage is limited memory resources. , not suitable for storing large amounts of data; 2. Database caching refers to storing data in a database system, improving data through query optimization, indexing and other technologies, etc.

- What are the java caching mechanisms?
- Java cache mechanisms include memory cache, data structure cache, cache framework, distributed cache, cache strategy, cache synchronization, cache invalidation mechanism, compression and encoding, etc. Detailed introduction: 1. Memory cache, Java's memory management mechanism will automatically cache frequently used objects to reduce the cost of memory allocation and garbage collection; 2. Data structure cache, Java's built-in data structures, such as HashMap, LinkedList, HashSet, etc. , with efficient caching mechanisms, these data structures use internal hash tables to store elements and more.

- How to implement underlying concurrency processing in PHP
- How to implement concurrency processing at the bottom of PHP requires specific code examples. In the process of web development, it is often necessary to handle a large number of concurrent requests. If concurrent processing is not used, problems such as long response times and excessive server pressure will occur. PHP is a language for web development. Its built-in multi-threading support is relatively weak, but it can achieve underlying concurrency processing through other methods. 1. Principle introduction In PHP, each request will be processed by a new process or thread opened by the web server. In order to improve concurrency capabilities, at the bottom
