What is the best way to manage the growth of the default storage location in a shared workspace? I have a number of users logging in and working on different clusters in a single workspace. I understand that all the results and notebooks are saved to the default storage location. The location seems to grow quite rapidly. The users don't store delta table data in the default location as well.
