one. Preface PROCEDURE ANALYSE(), which can be used as an auxiliary reference to analyze statements when optimizing the table structure. Using this statement, MySQL helps you analyze your fields and their actual data, and will give you some useful suggestions. [These suggestions will only become useful if there is actual data in the table, because making some big decisions requires data as a basis. ] For example, if you create an INT field as your primary key, but there is not much data, then PROCEDURE ANALYSE() will recommend that you change the type of this field to MEDIUMINT. Or you're using a VARCHAR field, and since there's not much data, you might get a message asking you to change it to ENUM suggestions. These suggestions are all possible because there is not enough data, so the decision-making is not accurate enough. When we design a table, we sometimes always think about what type to use for a certain field. A novice-level PHPer will have considerable experience and can type it out directly. In fact, we can also use procedure analyze(); analysis during later tuning.

Explain the InnoDB Buffer Pool and its importance for performance.Explain the InnoDB Buffer Pool and its importance for performance.Apr 19, 2025 am 12:24 AM

InnoDBBufferPool reduces disk I/O by caching data and indexing pages, improving database performance. Its working principle includes: 1. Data reading: Read data from BufferPool; 2. Data writing: After modifying the data, write to BufferPool and refresh it to disk regularly; 3. Cache management: Use the LRU algorithm to manage cache pages; 4. Reading mechanism: Load adjacent data pages in advance. By sizing the BufferPool and using multiple instances, database performance can be optimized.
