I’m running Rocket Chat version 1.0.3 via Snap on a Raspberry Pi 4. Following the instructions [here](https://github.com/RocketChat/Rocket.Chat.RaspberryPi) it states in Prerequisites: `the fastest and largest capacity microSD you can get, we recommend 128GB Class 10 or higher` However, when i run Mongo installed within Snap is states: ``` NOTE: This is a 32 bit MongoDB binary. 32 bit builds are limited to less than 2GB of data ``` Can i understand why so much disk capacity is needed if this is the DB constraint?
