I am looking at different ways of storing settings for an ESP MicroPython MCU with the settings being larger than what can be stored in EEPROM.

My main question is: If I store the large JSON formatted settings file on an external server that the ESP can pull from, can the ESP parse settings from that JSON file even if the whole JSON file is larger than onboard memory?

I guess I am asking if MicroPython urequests library has a memory limit and does the MCU need to download the entire JSON file to onboard memory? Has this been done before?
