Understanding these differences is important to understanding how to get good performance out of either. Previously, PostgreSQL’s running performance was really balanced – read operations were generally slower than MySQL, but it has the capacity of writing large amounts of data more efficiently when hardware resources are compared to MySQL and it always handled concurrency better. It can scale to nearly any sized application (as evidenced by its use by Facebook) and it's easier to find experts and support in MySQL. On the other hand, in recent years PostgreSQL has also been optimized to erase the differences when it comes to heavy data writes.Concurrency in DBMS systems means that more then one users can access the same data at the same time. Previously, PostgreSQL’s running performance was really balanced – read operations were generally slower than MySQL, but it has the capacity of writing large amounts of data more efficiently when hardware resources are compared to MySQL and it always handled concurrency better. Comparez PostgreSQL à MySQL. MySQL est système de gestion de bases de données relationnelles (SGBDR) open source tandis que PostgreSQL est un système de gestion de base de données relationnelle orienté objet puissant et open source. While historically PostgreSQL had a performance increase over MySQL, these days the difference in performance is negligible, so performance should not be a factor when choosing between the two. But certainly one year of extra development would not account for such a sharp contrast in popularity. Overall, the ease of use of MySQL and the fact that it has grown in popularity due to its connection with Oracle has contributed to MySQL having a larger market share than PostgreSQL.While historically PostgreSQL had a performance increase over MySQL, these days the difference in performance is negligible, so performance should not be a factor when choosing between the two. It can also run on nearly any OS, and It uses basic SQL rather than a specialized variant which makes it easier for novice users to utilize. Default MySQL package has also been replaced by MariaDB in Debian software repositories as it gets no updates.A Computer Science Graduate, who works extensively on open source projects. L a différence entre PostgreSQL et MySQL est une décision importante lorsqu’il s’agit de choisir un système de gestion de base de données relationnelle open-source. However, both PostgreSQL and MySQL can perform master-slave replication, in which one node is the master and controls data storage by the other nodes. On the contrary, there are some drawbacks such as: When it comes to popularity, it’s no way near MySQL. PostgreSQL better implements a lot of the things that oracle does in an open source environment even though MySQL is owned by oracle. If you really have to choose running between PostgreSQL vs MySQL for a new development project. Nous vous suggérons d’essayer ce qui suit pour trouver ce que vous recherchez :Que choisir entre MySQL, un système de gestion de bases de données relationnelles (SGBDR) open source et PostgreSQL, un système de gestion de base de données relationnelle orienté objet et open source ?
Si vous souhaitez que votre cluster Posgres ait davantage de performance ou encore de capacité, vous pouvez exploiter des techniques de regroupement, de réplication et de mutualisation mais cela s’avéra complexe. 3. MySQL also forms the M in the "LAMP stack" which is generally how simple web servers are configured (Linux, Apache, MySQL, and PHP). MySQL Performance Analyzer is an open source project for MySQL performance monitoring and analysis; Pome: Postgres monitoring dashboard. Some of the key features of PostgreSQL include:Once you've ordered a new server, it's time to set it up and secure it.
