Databases for scalable platforms?

Question

What database would you use to create a large platform for lots of users and lots of data?

Could you tell me which ones are the most used by the most popular platforms?

Answer 1

It would depend on many other things too. First of all, how much is "lots of data"? Thousands, millions of records? Or even terabytes / petabytes? How complex is the data structure, how many fields you need to store and how they are related. Is the structure of the data more or less constant, or it changes rapidly? Do you need redundancy, disaster recovery, high availability? Are you OK with eventual consistency? Once the data is created, does it ever change or stays immutable? How long do you have to keep it: for a few minutes, or days, or years? How often do people access it? Do you need to do expensive computations on the data?

All those questions influence the most ideal type of database for the project, and even then you may have several tech choices.
