That's an interesting find  @elizeu_reis , let's see what DBX folks come up back with on that.

Here are my two cents re I see that autotermination_minutes defaults to 60 minutes 
 -> if one happens to be creating a personal compute (not serverless) in Databricks, the initial setting of termination of the cluster set to 4320 mins and (which equals to 3 days...what a lovely Easter egg :D!) So one needs to keep in mind to change it to something around 20 mins instead right away and once done with their work switch the cluster off best.
