Issue
I wanted to know if Appsmith, a platform I am using, uses persistent storage in Kubernetes and what is stored in it. I also wanted to know if it can use a database instead of using the filesystem for MongoDB data.
Resolution
Appsmith uses persistent storage in Kubernetes to store MongoDB data and repos for git-connected applications. The MongoDB data includes users, workspaces, and applications. Appsmith can use a custom MongoDB as well. However, for git-repos, it needs access to the filesystem.
