MySQL is more popular than PostgreSQL on a variety of metrics: If those arise, you’re better off with a completely different solution to meet your needs, such as developing your own query language to handle large volumes of data.

And, unless you have extreme data needs (on the level of Netflix, Facebook, and other tech giants), you will barely notice performance issues. PostgreSQL performance is utilized to the fullest in systems that expect heavy analytic workloads. Why does this matter?įor most use cases, both MySQL and Postgres are going to be similar in performance. These (and other features) position Postgres as a better choice than MySQL for analytically heavy operations. A larger assortment of triggers, helping you to govern the constraints of your CRUD operations.But unlike MySQL, Postgres boasts a wider range of indexes, such as partial indexes (used for filtering data), bitmap indexes (efficient when working with categorical data), and expression indexes (indexes as a function of other columns). Both Postgres and MySQL implemented several indexes, such as full-text indexes for full-text search, or automatically indexing primary keys for fast speed row retrieval. Indexes - indexes allow the RDBMS to execute CRUD operations faster.This speeds up complex or nested SQL queries by several orders of magnitude.

Materialized views - allow you to save the results of an analytic SQL query as its physical table on disk, which can be more efficiently addressed by other SQL queries.

One point of difference which remains noteworthy is the performance features that are unique to Postgres: However, with each new update, their performance at the read-write level is becoming increasingly comparable between the database systems. a simple BI system for your e-commerce store), while Postgres shined in complex OLTP/OLAP systems but used more memory (each new Postgres process is allocated 10MB). People often try to compare MySQL and Postgres on their level of performance - in other words, how fast and how well they realize their functions.įor decades, it was common knowledge that MySQL was better at read-heavy operations (e.g.

Allow other programs to utilize CRUD operations (e.g.

Optimize CRUD operations in the background (abstract from users).

CRUD (create, read, update, delete) operations on data.

An RDBMS is expected to perform a variety of functions: Comparison #1: Performanceīoth Postgres and MySQL are relational database management systems (RDBMS), which means that they store data in the relational (tabular) model.

We offer a completely free tier of our data-stack-in-one platform. To make your decision easier, we’ve provided a side-by-side comparison of two of the most popular databases - Postgres and MySQL - across a range of criteria: Choosing the right database from the very beginning can offset and mitigate problems that arise later on, such as limited analytics and the lack of support. In non-tech terms: they’re like Excel but with added features… so more of an Excel on steroids.įrom storing a digital representation of all your purchasing orders to analyzing performance metrics, RDBMS were developed to facilitate working with data at scale.īut not all RDBMS were created the same. The relational model organizes data as tables of rows and columns. The “relational” part of the name refers to the database architecture, which structures data according to the relational data model. They are complex technological inventions designed to simplify your data operations across a wide variety of business use cases. PostgreSQL (or Postgres) and MySQL are both relational database management systems (RDBMS for short).
