   In most scenarios, I think the time partition to hour should be enough. If timestamp is used to partition for 15 minutes, the following phenomena may occur:
   1. There will be more file directories
   2. There will also be more small files than other partitions (hour/day/month/year)
   3. In a production system, is it common to divide time into minute granularity?
   
   The above is just my opinion, welcome more others to leave good suggestions and opinions.
