How do you optimize database schema design for performance in MySQL?
Article Introduction：Optimizing database schema design in MySQL can improve performance through the following steps: 1. Index optimization: Create indexes on common query columns, balancing the overhead of query and inserting updates. 2. Table structure optimization: Reduce data redundancy through normalization or anti-normalization and improve access efficiency. 3. Data type selection: Use appropriate data types, such as INT instead of VARCHAR, to reduce storage space. 4. Partitioning and sub-table: For large data volumes, use partitioning and sub-table to disperse data to improve query and maintenance efficiency.

MySQL Database Cost Optimization Strategies
Article Introduction：MySQL database cost optimization mainly revolves around resource utilization and performance efficiency. 1. Reasonably select cloud service packages, select appropriate configurations by monitoring load conditions, give priority to memory instances and use reserved instances to save costs; 2. Optimize query and index design, avoid SELECT*, reasonably use combined indexes, and regularly analyze slow query logs; 3. Implement data archiving and database sub-table strategies, move cold data to low-cost storage, and perform horizontal sub-tables to reduce single-node pressure if necessary; 4. Use cache to reduce database pressure, cache hotspot data through Redis, reduce the number of connections and requests, and improve system stability. Continuous observation and gradual adjustment are the key to achieving long-term cost control.

Approaches to Scaling MySQL Database for High Load
Article Introduction：The MySQL stand-alone bottleneck can be solved through read and write separation, library separation, cache and asynchronous processing and other optimization methods. 1. Read and write separation is realized through master-slave replication. The main library processes write requests, and the slave library processes read requests, and combines connection pools to improve efficiency, but attention should be paid to the asynchronous replication delay problem; 2. The sub-repository sub-table includes vertical split (split by field) and horizontal split (split by rules), which is suitable for large data scenarios and requires middleware to handle complex queries; 3. Caching can reduce database pressure, use Redis or Memcached to cache hotspot data, and combines message queues to asynchronously process non-real-time write operations; 4. Other optimizations include slow query analysis, parameter tuning, connection pool management and SQL optimization, and detailed processing is crucial to performance improvement.

MySQL Connection Pooling Strategies for High Concurrency
Article Introduction：Reasonably set the maximum number of connections, control waiting and timeout mechanisms, maintain healthy connections, and optimize management under sub-store and tables. The configuration of MySQL connection pool is crucial under high concurrency. The maximum number of connections should be slightly lower than the database upper limit and combined with monitoring adjustments. ConnectionTimeout and SQL execution timeout mechanisms need to be set to prevent thread accumulation; connection detection and idle recycling mechanisms are enabled to ensure connection effectiveness; in scenarios such as read and write separation or database separation and table separation, each data source should independently configure connection pools and adjust the size according to traffic allocation to improve overall performance and stability.

Integrate MySQL data into HTML tables and implement single-line data transfer and processing
Article Introduction：This article explains in detail how to display the data queried from the MySQL database in an HTML table, and when a specific button in the table is clicked, the data of the corresponding row (usually a unique identifier ID) is safely and efficiently passed to another PHP page for subsequent processing (such as editing). The tutorial covers key steps and security practices for front-end HTML link building, URL parameter passing, and back-end PHP using PDO for parameter verification and database query.
