It’s difficult to reuse or build upon tables in a MySQL database. This comes at a cost, however, because it requires additional computation to build object oriented, or OO-based, structures. This allows Postgres to define objects and inherit tables, paving the way for more complex structures. MySQL is a relational database management system (RDBMS), whereas Postgres is an object-relational database management system. For a simple implementation, then, Postgres would be a poor choice! Database Structure Thus, it sacrifices speed for data integrity and standards compliance. This causes bloated memory usage and effectively eats away at speed. This is because Postgres allocates a significant amount of memory (about 10MB) when it forks a new process for each connection. Since most applications only read and display information from a database, there have been many times when a simple MySQL implementation far outperformed a PostgreSQL implementation. One area where MySQL excels, however, is in read-heavy operations. In order for MySQL to scale in production environments, you will have to add a considerable amount of resources. This essentially reduces the number of concurrent operations per process. On the other hand, MySQL tries to achieve concurrency with the use of write locks. It is also fully ACID compliant and implements transaction isolation and snapshots. Postgres inherently performs better due to its concurrent support for write operations without the need for read/write locks. It’s used by the likes of Wikipedia, Google, NASA, and Tesla! Since MariaDB is a fork of MySQL, you do not have to make any major changes, and you can easily port over your existing sources and data. It was built by the original developers of MySQL and is guaranteed to stay open source (unlike MySQL, which is maintained by Oracle although it is open source). MariaDB is a popular alternative to MySQL. Has lots of support for NoSQL and more data types Object-Relational Database Management System Read on for a deep-dive into the critical distinctions between them. These differences stem from the ways in which they were originally built. As a general rule of thumb, MySQL is better for website and transactional traffic, while PostgreSQL is great for analytical and concurrent processes. In most real-world scenarios, MySQL and PostgreSQL have comparable performance, though in applications that are more read-heavy, MySQL outperforms PostgreSQL by a wide margin. Key Differences between MySQL and PostgreSQL In addition, its heavy emphasis on safety and security inspired unique features such as transaction snapshots, asynchronous notifications, and triggers. What is PostgreSQL?Īlthough Postgres is just a year older than MySQL, it’s advertised as “the most advanced open-source relational database in the world.” It is an object-relational database, which makes it easier to work with in modern web frameworks. MySQL is known for its performance in read-heavy workloads, though it fizzes out during concurrent write operations. It is a traditional relational database and uses tables as its core structure. The first version of MySQL was released in 1995, and it continues to be the standard choice for both beginner and advanced developers. So why are they so widely used and how do they compare? Read on to find out! What is MySQL? These systems were developed back in the mid 90’s, and they still consistently rank among the top 5 most popular databases across the internet. Despite all of the hype about NoSQL databases, MySQL and PostgreSQL are two database management systems that have truly stood the test of time.
