This article might help, when you have to face the MySQL (or MariaDB) vs. PostgreSQL question. I think the licensing point is particularly important in the system integration world.

We use MariaDB and it has been pretty awesome for us so far. Especially if you are able to utilize TokuDB compression. Historian data is compressed substantially.

The Database Module embeds the H2 SQL database engine into Ignition. It is the easiest and fasted way to get started using databases in Ignition.

SQLite is also a very good option, it’s extremely lightweight and easy-to-use.
