Large Registry on CMS under MySql?

Question

CMS

The task is to create a Register of Pensioners, so that at the same time from different parts of the country they add data with their own specific "rights".
Is it worth creating something similar on some CMS under MySql? and will MySql pull data up to 2-3 million people? because there will be a search and all that in this platform.
Or maybe there are other solutions?
As far as I can see - within the framework of the web platform, perhaps this task is solved differently?
Tell me please.
Thank you!

Answer 1

No. Take some framework like Yii2, Laravel, etc.
And it will pull many times more. Here everything depends more and more on the directness of the hands of the programmer.
By the way, what is stopping you from filling the database with fakes and trying to work with it?
Thousands of them.
PS
Well, in general, yes, this can be done on CMS, for example, on ModX or Joomla. But a person who can normally solve such a problem is more likely to take a framework.
