SYSBENCH 既可以用于测试 MySQL 的性能，也可以用来测试 PgSQL 的性能（当然也包括两者的兼容衍生），因...
Replication is asynchronous, which can pose challenges in terms of performance and scalability. A key advantage of MySQL replication is that replicas are not read-only; if an application fails over to a replica when a primary database crashes, the replica can consume both reads and writes...
PostgreSQL单机性能比MySQL要好，优化器比MySQL强，当年各大互联网公司选择MySQL，主要是其复制功能太弱鸡...
MySQL — a fast, reliable, scalable and easy-to-use open-source relational database system — is designed to handle mission-critical, heavy-load production applications. It is a common and easy-to-start database with low memory, disk and CPU utilization, managed by a relational database mana...
PostgreSQL, also known as Postgres, advertises itself as “the most advanced open-source relational database in the world”. It was built to be feature-rich, extendable and standards-compliant. In the past, Postgres performance was more balanced - reads were generally slower than MySQL, but it...
PostgreSQL est implémenté sur un seul serveur et ne distribue à priori pas ses fonctions de stockage ou de calcul sur plusieurs nœuds. Si vous souhaitez que votre cluster PostgreSQL ait davantage de performance ou encore de capacité, vous pouvez exploiter des techniques de regroupement, ...
MySQL 在功能上缺失的绝不仅仅是是编程语言/存储过程支持,在各个功能维度上,MySQL 都落后它的竞争对手 PostgreSQL 太多了 —— 功能落后不仅仅是在数据库内核功能上,更发生在扩展生态维度。 来自CMU 的 Abigale Kim 对主流数据库的可扩展性[14]进行了研究:PostgreSQL 有着所有 DBMS 中最好的可扩展性(Extensibility...
在学习具体的Postgresql用法之前,我们来思考一下Postgresql与目前最常用的关系型数据库MySQL的区别在哪里,主要集中在两者的底层结构、使用场景和特别之处。 1.前言 当我们去选择项目使用的数据库的时候,应该要考虑该项目的应用场景、数据规模等因素。每一种数据库都有它特定的应用场景,比如我们现在要讨论的Postgresql和My...
MySQL, on the other hand, was first released in 1995 and has been widely used for web-based applications due to its high performance and ease of use. Over time, Oracle acquired the open-source database management system MySQL and turned it into a commercial product. ...
(/significant-performance-boost-with-new-mariadbcompression-on-fusionio/)更新的开销另一个经常被忽略的特性,但是对性能有很大的影响,并且可能是最具争议的话题,是更新。这也是Uber放弃Postgres的另一个原因,这激起了许多Postgres支持者的反驳。MySQL对Uber可能是合适的,但 10、是未必对你合适/articles/on-ubers-...
