The ACID model is a set of database design principles that emphasize aspects of reliability that are important for business data and mission-critical applications. MySQL includes components such as the InnoDB s
If you follow best practices for database design and tuning techniques for SQL operations, but your database is still slow due to heavy disk I/O activity, consider these disk I/O optimizations. If the Unix top tool or the Windows Task Manager shows that the CPU usage percentage with your...
A: MySQL NDB Cluster is built on the NDB storage engine and provides a highly scalable, real-time, ACID-compliant transactional database, combining 99.999% availability with the low TCO of open source. Designed around a distributed, multi-master architecture with no single point of failure, MySQ...
These days, there’s significant industry interest in moving database systems to PostgreSQL. Often, these are greenfield projects focusing on design and architecture. However, decisions are increasingly being made to move from existing platforms, like MySQL, to PostgreSQL for compelling business and ec...
mysql 数据库是被广泛应用的关系型数据库,其体积小、支持多处理器、开源并免费的特性使其在 Internet 中小型网站中的使用率尤其高。在使用 mysql 的过程中不规范的 SQL 编写、非最优的策略选择都可能导致系统性能甚至功能上的缺陷。 恰巧就在前几天,本人所在公司的云事业部举办了一场关于 mysql 的技术交流会,其...

2. Data Nodes:存储层的NDB节点,即Cluster环境下的存储引擎。每个cluster节点保存完整数据的一个分片,视节点数目和配置而定,一般data nodes被组织成为一个个group,每个group存有一份完全相同的物理数据(冗余)。NDB存储引擎首先按照冗余参数配置来使用存储节点,然后根据节点数目对数据进行分段 ...
When you use a Flexible Server architecture, you can opt for high availability within a single availability zone or across multiple availability zones. Flexible servers are best suited for: Ease of deployment, simplified scaling, and low database-management overhead for backups, high availability, ...
