Does SQLite use RAM?

Is SQLite stored in RAM?

An SQLite database is normally stored in a single ordinary disk file. However, in certain circumstances, the database might be stored in memory. The most common way to force an SQLite database to exist purely in memory is to open the database using the special filename ":memory:".

Is SQLite in memory fast?

Besides SQLite is just a really fast database. Faster even than most server databases.

Is SQLite memory efficient?

Depends on the strings are and what you need them for. If they vary each time the app runs, leaving them in memory, as a string array, is probably best. If they are persistent between app runs, the sqlite DB will probably be better in the long run since you don't need to "reload" the database between app runs.

Does SQLite cache in memory?

SQLite provides an in-memory cache which you size according to the maximum number of database pages that you want to hold in memory at any given time. Berkeley DB also provides an in-memory cache that performs the same function as SQLite.
