How to cache some data explicitly ?

[kavink]

After I read some big json file from somewhere, I want to make that internally available by my app to work on it, Or when user queries it to return from cache, I can use @cache.memoize() on get function for user to use and for my app to use, But there is a one time hit of getting the json from my DB.

As I am populating that data myself, is it possible to populate that in cache explicitly so my app just uses that ?

Not sure if I understood you correctly, but you could use these functions to modify the cache 'directly'.

@sh4nks I've the same question - it's not immediately clear how to access the cache directly from any place in the Flask application.
For example, the following doesn't work (not that it should; I'm just trying to figure out how to use it!):

from flask import current_app


def set_default_cache_value_in_helper_file():
    with current_app.app_context():
        current_app.cache.set("some_key", "some_value")
