Abstract: Systems and methods of maintaining a horizontally scaled database based on data ownership for a cloud-based platform (e.g., cloud-based collaboration and/or storage platform/service) are disclosed. The system database comprises multiple shard databases, and all files and folders owned by a user are stored on a single shard database. When a user transfers ownership of a file and/or a folder to a second user, the transferred file and/or folder is stored on the shard database that stores all of the data for the second user.

Abstract: Systems and methods of batch uploading of content to a web-based collaboration environment are disclosed. In one aspect, embodiments of the present disclosure include a method, which may be implemented on a system, for receiving an upload request from a user through a user interface to upload multiple items and sequentially uploading each of the multiple items to the host server. In one embodiment, the user is able to navigate away from the user interface through which the upload request was submitted prior to completion of the uploading of each of the multiple items to the host server. In addition, the upload of the multiple items is not interrupted if the user accesses a link on the user interface causing another user interface to launch in a browser.
