Clustered columnstore indexes
In the last sections of this chapter, you will learn how to manage a CCI. Besides optimizing query performance, you will also learn how to add a regular B-tree nonclustered index (NCI) to a CCI and use it instead of the primary key or unique constraints. When creating the NCCI in the previous sections, we didn't use LZ77 or archive compression. You will use it with a CCI in this section. Altogether, you will learn how to do the following:
- Create clustered columnstore indexes
- Use archive compression
- Add B-tree NCI to a CCI
- Use B-tree NCI for a constraint
- Update data in a CCI
