Hi There;
I am reading some content about the data warehouse, and I encountered a phrase as such:
(context) Hardware and I/O Considerations in Data Warehouses --> Automatic Striping -->
"For index probes (for example, within a nested loop join or parallel index range scan), operating system striping enables you to avoid hot spots by evenly distributing I/O across the disks." http://docs.oracle.com/cd/B10500_01/server.920/a96520/hardware.htm
what is hot spot? Could you please explain briefly; Thanks in advance.
