MariaDB vs Postgres

Open-source RDBMS (Relational Database Management System) such as Postgresql or MariaDB are likely to be at the top of the list when a company is looking for a new RDBMS (Relational Database Management System). Each database has its own set of advantages and disadvantages, making a Postgresql vs MariaDB head-to-head comparison difficult.

MariaDB is an open-source relational database management system that is a drop-in replacement for the popular MySql Database Technology.

MariaDB vs Postgres

PostgreSQL is a high-performance, enterprise-class open source relational database that supports SQL (relational) and JSON (non-relational) querying.

In this sub-topic, we will differentiate between Postgresql and MariaDB with the help of examples.

Features MariaDBPostgresql
Size It’s best for databases with fewer records.It is appropriate for a larger database.
Data TypingIt’s a useful data type.It is a strict data integrity policy.
ReplicationIt’s both adaptable and powerful.Only Master slaves are allowed.
Partitioning Access to partitioned data is now faster.It doesn’t support the partition of data.
NoSQL and JSONIt’s not completely supportedAppropiate for NoSSQL database.

MariaDB vs Postgres Performance

In this section, we will know and take the difference between the performance of MariaDB and Postgres.

MariaDB has a smaller memory footprint than PostgreSQL because it is a smaller database. In terms of reads and writes, PostgreSQL exceeds MariaDB, making it more efficient.

MariaDB is better suited for smaller databases and can store data entirely in memory, which PostgreSQL lacks. PostgreSQL outperforms MariaDB’s query cache by retrieving frequently used data from an internal cache and the server’s page cache.

MariaDB vs Postgres Which is better

In this section, we will discuss which database programming language is better between MariaDB and Postgresql.

Let’s break the WHICH question for MariaDB and Postgresql into two parts:

  1. When to use MariaDB over Postgresql :

MariaDB allows for datatype flexibility, however when adding and updating data with the INSERT INTO and UPDATE statements, it properly converts data into the correct datatype. We can use this, but we must be cautious about the schema used by the application for the data.

It also supports MASTER-MASTER replication, making it excellent for applications that require high availability and low latency.

2. When to use Postgresql over MariaDB:

Additional features in Postgresql, such as materialised views and partial views, improve efficiency. For expensive joins and aggregations that can be done fast, the materialised view can be employed.

For every record in a table, indexes are built, which are costly to develop and maintain but allow an index to be created. When there is a lot of data, partial indexes are usually entered or constructed.

If we put as a conclusion about MariaDB and Postgresql as which one is better? cause there are advantages and disadvantages to both MariaDB and Postgresql. Ultimately choose the right database based on the system requirements and which database can fulfil your needs that all depends on you only.

MariaDB vs Postgresql vs MongoDB

In this sub-topic, we will discuss the differences between MariaDB Database and Postgresql Database, and the MongoDB NoSQL database.


MariaDB is considered as a replica of the MySQL database. MariaDB, which carries more extra functions to the MySQL engine, was developed by the same MySQL developer.


PostgreSQL is an ORDBMS-based alternative to MySQL (Object-Relational Database Management System). As a database server, its primary function is to securely store data while following guidelines, and then retrieve it when other software applications, whether on the same computer or another computer over a network, demand it.

In terms of performance and redundancy, the effective plan outperforms MySQL.


MongoDB is a document-oriented database that runs on multiple platforms. It is a specialized database that can handle any form of file or element and is built on a non-relational document store architecture identical to JSON. It provides faster data processing and a shorter response time for a specific application.

These three databases are used on different applications based on need. The difference between MariaDB, Postgresql, and MongoDB is given below:

BasicsIt is the free alternative to MySQL, with very similar scalability and adaptability capabilities. Its strength is remarkable.MariaDB is a database system that was created as a derivative of MySQL.
All MySQL commands, interfaces, libraries, and APIs are also available in MariaDB.
MongoDB is the most popular non-relational database system these days, owing to the speed and flexibility it provides to your initiatives.
It has a syntax similar to JSON and may store any type of element: objects, physical files, and so forth.
Database TypeThe RDBMS database is a built-in table format.The Relational Database Management system is created in table format.Database in the form of a document sheet, with some records including nested entries.

MariaDB vs Postgresql Memory Usage

In this sub-topic, we will discuss the memory usage of both MariaDB and Postgresql and it is explained below as a difference.

Another major difference between MariaDB and Postgresql is system size and partitioning. Based on the system, the MariaDB system is smaller than the Postgresql system based on the OS versions. The memory allocation is shorter in MariaDB and the database is also lighter than the Postgresql database.

If we compare based on partitioning in between MariaDB and Postgresql then the MariaDB database uses various partitioning techniques whereas the Postgresql there is no partitioning.

MariaDB vs Postgresql Comparison

In this section, let’s discuss the top comparison between MariaDB and Postgresql by using the table as given below:

DescriptionThe MariaDB is a MySQL application that is an open-source application and has high-performance capability, security, and high availability.Postgresql is an open-source relational database management system that is used to store data.
Initial- ReleaseThe first release was launched in the year 2009 in Delaware, U.S.A.The first release was launched in the year 1989 at the University of California, Berkeley.
Implementation of languageThe language used to make the MariaDB is C and C++ programming language.The language used to make the Postgresql is the C programming language.
Server Operating SystemThe server operating system supported by MariaDB is Solarix, Windows, Linux, and FreeBSD.The server operating system supported by Postgresql is Solaris, Windows, FreeBSD and Linux, NetBSD, Unix, OpenBSD, and many more.
Server-side scriptsIn the MariaDB system, they are defined and can be used during data storage.In the Postgresql system, the user can define the function as per requirements whereas this feature doesn’t support in the MariaDB system.
Partitioning MethodsThe partition method which is used in the MariaDB system is horizontal partitioning,  Galera cluster, and sharding with the spider storage engine.The partition method which is using the Postgresql system is list, hash, and range.
In-memory capabilitiesThe MariaDB system supports in-memory capabilities and it is also lighter than the PostgreSQL system.In the PostgreSQL system, it doesn’t support in-memory capabilities.
JSON supportIt doesn’t support the JSON support but it uses the LONGTEXT column that works similiasimilarN support.The PostgreSQL supports both JSON and JSONB support.

MariaDB columnstore vs PostgreSQL

In this sub-topic, we will discuss both the database columnstore of MariaDB and PostgreSQL.

MariaDB columnstore:

It is a column-store engine that utilizes massively parallel circulated data architecture and it is a storage engine for the MariaDB server which comes from MariaDB 10.5.4 version.

The MariaDB columnstore is built for big data scaling, with the potential to manage petabytes of data, linear scalability, and great performance with real-time response to analytical queries. It takes advantage of the I/O advantages of columnar storage, compression, just-in-time projection, and horizontal and vertical partitioning to give an exceptional performance while processing massive data sets.

PostgreSQL columnstore:

The PostgreSQL columnstore provides a more performant way for PostgreSQL to retrieve data from a large table in queries that are used as a subset of all columns in the table. It helps in improving query and reporting performance, especially at a high scale for users. With the help of implementation, data warehouses and analytical databases are free to open source in Postgresql.
