In-memory storage for flask application

Question

My flask application stores some data in a database. I want this data to be discarded if my application has been down for some time. The reason for this is that I want to be sure that I missed no REST call to my application.

The obvious and efficient solution is storing this data in memory but I am open to any solution (e.g. delete old records on application restart).

Answer 1

If you don't need persistence in your application, why don't you use the SQLite backend (easy in flask) and store the database in memory (using the :memory: filename as data base), then on each shutdown your data will be cleaned.

Answer 2

You can use persisted memory-mapped files. Python has a facility (mmap) to work with such files.
