"You can store up to 30 million items or files in a SharePoint list or library. Filtered views of large lists have a similar experience to other lists. However, when a list view shows more than 5000 items, you may run into a list view threshold error."
I am one of those who consider not to go live with Sharepoint Online because of the threshold issue. You can store up to 30 million files in a library, but a fully functional view can only handle up to 5000 items.
A library should be designed to meet the needs of the end users and not focus on workarounds because of a technical issue.
The threshold should be increased significantly.
