Alternatives to MS SQL Server

Another good one. MySQL and MariaDB lack ACID compliance, which is huge. PostgreSQL is fully ACID and more SQL complete.
Also some performance numbers and notes. They reiterate, MySQL is good for web workloads where relational data isn't needed.

You know what I am benching them right now, hold on with me...

Everyone uses InnoDB currently so that is not an excuse, fresh installs on Centos 7(which people consider old) defaults to InnoDB
So it is ACID compatible 100%.
The use and assumption of InnoDB is VERY new and not what most knowledge and testing of MySQL or MariaDB are based on. MariaDB only just moved to it as the default. And even InnoDB is not 100% ACID, so that point is moot.
MySQL is anything but "everyone uses InnoDB". And InnoDB lacks ACID completeness.

What kind of workload?
-
WordPress company thinks MyISAM remains the dominant engine just weeks ago. I think you'll find InnoDB is only just starting to catch on. Anyone bringing databases of any age with them will almost always be on MyISAM as InnoDB was rarely recommended for decades.

sorry but what is "InnoDB is not 100% ACID", this is more of speculation than anything .
I tried to bench both, but I was unable to complete, I found good tool called Hammerbench.
It worked on MariaDB, but when I tried using it on PSQL, but I was unable to remote manage and connect to PostgreSQL,
cause their latest client does not support SSH tunneling, so I downgraded to 3, but that also didnt work, can I needed to configure this file:
nano /var/lib/pgsql/data/pg_hba.conf
I tried everything with the last lines
host all all 127.0.0.1/32 ident
host all all ::1/128 ident
like:
host all all 0.0.0.0/0 md5then restarted the service, with no use, I was unable to connect it remotely, thus the bench didnt resume.
What I can only tell you that is it is smaller download size thats it

That would mean it being ACID compliant is speculation as well. But if there is no way to know, then we must treat it as not ACID compliant.

This is how Oracle states it officially: "MySQL includes components such as the InnoDB storage engine that adhere closely to the ACID model,"

This is the closest I can find regarding this

Anyway the reason I say this I worked on packaging
Nginx
MariaDB
PHPon windows as standalone package @ 2013

when I was in university.So till now I admire how easy it was and how InnoDB was the right choice that you need to select, I did that back 5 years ago.
I will check Postgresql when I have more free time, it was peculiar to me that it was 20 mb download and install, instead of 100+ for MariaDB on Centos 7.

Didn't MariaDB just drop XtraDB to go back to InnoDB? I thought that they just announced it.

It depends on what you are doing. Lots of things that are done on MariaDB, like many PHP web apps, actually should be MyISAM rather than InnoDB. It was the default for a long time for a reason, it's screaming fast and if you are just doing simple reads most of the time, it's really good.
