请教个问题:通过sqlserver订阅发布来实现读写分离合理吗?

  

    为减轻中心数据库服务器压力,前置数据库服务器与中心数据库服务器数据交互实行读写分离。因此,需要多台数据库服务器进行支撑,将数据库服务器分为主数据库服务器、从数据库服务器。

    主数据库服务器主要负责写操作,各个场馆的前置数据库服务器发送数据同步请求(上传)时,主动选择主数据库服务器执行数据更新(插入、更新)命令。

    主数据库服务器与从数据库服务器之间,是一个订阅发布的关系。主数据库服务器发布指定的表,从数据库服务器数据库订阅主数据库服务器发布的表,实现数据库之间的同步。所有数据只有insert、update操作,没有delete操作。

     从数据库服务器主要负责读操作,前置数据库服务器发送数据请求(下载)时,主动选择从数据库服务器读取符合条件的数据,下载到前置数据库服务器进行更新操作。

MySQL: String Data Types and Indexing: Best PracticesMySQL: String Data Types and Indexing: Best PracticesMay 12, 2025 am 12:11 AM

Best practices for handling string data types and indexes in MySQL include: 1) Selecting the appropriate string type, such as CHAR for fixed length, VARCHAR for variable length, and TEXT for large text; 2) Be cautious in indexing, avoid over-indexing, and create indexes for common queries; 3) Use prefix indexes and full-text indexes to optimize long string searches; 4) Regularly monitor and optimize indexes to keep indexes small and efficient.
