The advantage of using jsonb is that you can easily integrate relational and non-relational data. So if you have software that relies on the order of the keys, jsonb may not be the best choice for your application. Unlike jsonb, which is stored in binary format and does not guarantee the order of the keys. json columns parse the stored values each time, which means that the keys are in the same order as they were entered. When we compare the speed of writing data, jsonb is slightly slower than json because of the way the data is stored. It supports indexes, which means you can query any path without using the specified index. jsonb stores in binary format, which avoids re-parsing the data structure.json stores finished text, json columns parse the stored values each time, it does not support indexes, but you can create expression indexes for queries.Jsonb and json look almost the same at a higher level, but are different in their store implementations. json (hStore) and jsonb, which are much more efficient than using text to store transfers.array, whether it’s a one-digit array or a multi-digit array.In addition to storing normal data types, it also supports storing. Such two backgrounds lead directly to the inherent strengths and weaknesses of each. This makes MySQL’s development process more deliberate, while PostgreSQL is more responsive. MySQL is backed by a well-established commercial company, while PostgreSQL is backed by a large volunteer development group. postgreSQL is based on a free BSD/MIT license, and organizations can use, copy, modify and redistribute the code, requiring only a copyright notice. It offers a single full-featured version, unlike MySQL, which offers several different community, commercial and enterprise editions. Originally developed at the University of California, Berkeley in 1985 as a successor to the Ingres database, PostgreSQL is a completely community-driven open source project. some fans of PostgreSQL say it rivals Oracle, and without the expensive price tag and arrogant customer service. PostgreSQL touts itself as the world’s most advanced open source database. The core code is based on the GPL license, and because MySQL is controlled by Oracle, the community is concerned about the impact on MySQL open source, so some branches have been developed, such as: MariaDB and Percona. Oracle supports several versions of MySQL: Standard, Enterprise, Classic, Cluster, Embedded and Community, some of which are free to download and some of which are paid for. MySQL was originally developed by MySQL AB and then sold to Sun in 2008 for $1 billion, which was acquired by Oracle in 2010. MySQL is used by applications built on LAMP, such as WordPress, Drupal and most php open source programs. MySQL claims to be the most popular open source database, and the M in LAMP refers to MySQL. Before we start our analysis, let’s take a look at these two charts. MariaDB(MySQL) is good at dead simple query, however PostgreSQL is good at more complicated query.įor real world scenario, it will more likely has a lot of complicated query, therefore its better to choose PostgreSQL for it - provided that PostgreSQL comes with lots of useful feature that MySQL lack of.There are already many articles on the web comparing PostgreSQL with MySQL, this article is just to sort out some important information. SELECT * FROM testing WHERE word_col LIKE '%lim%' ORDER BY word_col DESC LIMIT 1000 SELECT * FROM testing WHERE int_col > 5000 ORDER BY word_col ASC LIMIT 1000 SELECT COUNT(*) FROM testing WHERE int_col + int_col2 > 12345 SELECT * FROM testing WHERE int_col + int_col2 > 12345 SELECT * FROM testing WHERE int_col > 5000 LIMIT 1000 Simple query: taking average of multiple time query Mariadb(mysql) write (10000 rows): from insert.sql, run 10x time accumulate to 100000 rows You can find the detail at my Repo Result Using similar table structure: located at _config.txt.To my surprise, most benchmark result is outdated, therefore I have decided to benchmark them, using MariaDB(MySQL) vs PostgreSQL How to Benchmark So recently I want to find benchmark for RDBMS between MySQL/MariaDB and PostgreSQL. Please Refer to updated benchmark on postgres vs mysql vs mariadb Choosing RDBMS I will update the correct benchmark soon. When using pgadmin, the execution time at status bar is including data transfer time, unfortunately, I am using pgadmin status bar execution time to compare with MySQL server execution time which is unfair.
