It is a must to extract a consistent set of row data in an ETL process. For MySQL, use the InnoD B storage engine to make use of MVCC. This is known in database management systems as Multiversion concurrency Control or MVCC. Concurrencyīoth PostgreSQL and MySQL can access a table row concurrently with many users. You may decide in favor of PostgreSQL if you need the data type not found in other relational databases. PostgreSQL has more types you can choose from. You can see the data types yourself using a tool like pgAdmin 4, shown below: For a long list of all supported types in PostgreSQL, check this out. So, aside from strings and numbers supported by PostgreSQL, it also supports XML, JSON, and more. Not to mention the errors you will encounter after wrongly mapping a handful of columns. That’s a lot of columns! Mapping them manually will be a pain. And then writing it to MySQL or PostgreSQL, for example. Imagine reading a Salesforce contacts table. And if your ETL tool does not map them automatically, you have to do it yourself. The headaches of data integration start when mapping incompatible types. Then, you will most likely see the language your team uses. You can check out this comprehensive list for MySQL. There are also native libraries for Python, PHP, Go, Ruby, Rust, C/C++, and many more. Or any language developer that supports the ODBC or JDBC. Data Access Libraries and Language Supportīoth MySQL and PostgreSQL support major programming languages and data access libraries.īoth database platforms got you covered if you’re a developer for Python, Java. For example, when you enable ONLY_FULL_GROUP_BY, the GROUP BY clause in a SELECT statement will behave differently. You can also set the SQL mode or behavior of MySQL. There are also many extensions added to it. MySQL’s goal is to comply with the latest SQL standard but not sacrifice reliability and speed. It differs from other SQL platforms like MySQL. But note also that there are extensions added to the standard. PostgreSQL conforms to 170 out of 179 mandatory features of the latest SQL standard. You need to note the compliance with the SQL standards of MySQL and PostgreSQLīecause the SQL syntax and behavior may differ if a standard is followed or not. Here’s a screenshot of it in Ubuntu Linux 22.04 using pgAdmin 4. PostgreSQL supports Linux, Windows, Mac OS X, Solaris, AIX, HP/UX, OpenBSD, FreeBSD, and NetBSD. So, if you plan to deploy a data warehouse made from either database, both are strong contenders. Major cloud providers like AWS, Azure, and Google Cloud have fully-managed database offerings for both. Your team of experts should have no problems deploying them. Installation and deployment are well documented for both databases. They also support both 64-bit and 32-bit architectures. PostgreSQL and MySQL support major operating systems whether in the cloud or on-premise. Other features are expanded in the next sections. Let’s discuss features that matter to data integration. And this is maintained by PostgreSQL Global Development Group. Meanwhile, PostgreSQL is known as the world’s most advanced open-source, object-relational database. MySQL is known as the world’s most popular open-source database. PostgreSQL vs MySQL Features Comparison.So, they need to adapt when the sources are one of these or both. They are sometimes forced to use either of the two database platforms. Your team of data professionals is not always lucky to choose the databases of their choice. Do you have a new data integration project that involves either PostgreSQL or MySQL? But if your team has never touched one or both, you need to read this PostgreSQL vs MySQL comparison.
