I am going to partition my data by date.
Can I separate latest data from historical data on daily basis?
I.e. I want rolling date window – say latest 30 days of data on one physical disk and the rest of them (older than that) on the another physical disk.
How do I roll it given the date data comes once in the morning?
Absolutely possible, when you define the partition schema, you indicate which file group each partition within that schema resides on.
The issue will come when you are rolling the data and need an entire partition moved from one disk to another – that operation will have to be performed carefully and depending on the data quantities could take some time.
Given only 2 physical disks are being mentioned, what is driving the need for that split?
