Partitioned Views With Memory-Optimized Tables

Ned Otter ran into an issue building partitioned views from a combination of disk-based and memory-optimized tables:

Let’s assume that we have two tables that belong to a partitioned view. Both tables can be memory-optimized, or one table can be memory-optimized, and the other on-disk.

Success condition

an UPDATE occurs to a row in a table, and the UPDATE does not change where the row would reside, i.e. does not cause it to “move” to another table, based on defined CONSTRAINTS

Failure conditions:

   a. UPDATE occurs to a row in the memory-optimized table that causes it to move to either another memory-optimized table, or a on-disk table

   b. UPDATE occurs to a row in the on-disk table that causes it to move to the memory-optimized table

Read the whole thing.  The good news is that if you’re splitting in a way that doesn’t require updating from one type of table to the other, partitioned views work fine.
