I am Working on an Android App, for which I use Parse as a backend[Parse-Heroku-Mlab (sandbox Plan)], this app provides different Services in the city, & the service owners complete information is listed in the App which also has User Images and icons.
Issue : When i try to upload images it doesn't gets uploaded(until last day it was working fine), but the text fields in the dashboard works and gets uploaded.
Parse Logs says : 2017-05-28T04:30:17.793Z - Could not store file. 2017-05-28T04:30:17.790Z - quota exceeded
Screenshots of Mongodb stats is attached.
Could it be that the issue is with Mlab.The sandbox plan gives the storage upto 512 mb. I tried freeing the space, but no go.
Try using a CDNfor storage like GCSAdapter or de S3Adapter. It is plain simple to set up. Old Images will continue work as normal.
Mlab calculates your quota by the fileSize value output from MongoDB. The size of an image can be from 3 to 12mb in modern phones.
