While searching for the features to find data size occupied by an application, I found below information.
Data Storage
- Data storage, can also be refered as File Storage File uploads | Bubble Docs, refers to files uploaded to an application and these files can be found in the Data → File Manager.
Anything that exists in the database (within the ‘Data’ → ‘App Data’ tab) does not count against file storage, and an app on a paid plan can have unlimited database things.
Data usage
Data usage refers to the amount of data transferred when your app interacts with Bubble’s servers.
This includes
- reading/writing data (from storage i.e file storage like upload and download),
- API calls, etc.
For data usage, Bubble.io measure this using workload units. Pricing and workload | Bubble Docs
