We're using SQL Server 2019. Our fact tables utilize datetime2
but I want to partition on year.
I don't have sysadmin privs so I can't set up different filegroups. I can create partition functions and partition schemes, but it isn't clear to me how to set up the partition scheme so that when I partition the table on ActivityLog
for example that it will store entries in their respective year partition.
I've searched the web and haven't found answers as to how it all works.

Partitioning by year on a datetime2 column in a fact table can be a useful technique for managing large data sets, improving query performance, and reducing maintenance costs. Here are the steps to set up partitioning by year:
This creates a fact table with a primary key that includes the partitioning column (DateColumn), and maps the partition scheme to the fact table's data filegroups.
Note that partitioning by year is just one option for partitioning a fact table, and the partition function and scheme would need to be adjusted accordingly for other partitioning strategies, such as partitioning by month, quarter, or some other time period.
