What is the difference between Clustered and Non-Clustered Indexes in SQL Server? Conclusion From the discussion we find following differences between clustered and non-clustered indexes. There can beonly one clustered index per table. However, you can create multiple non-clustered indexes on a sing...
Non-Clustered Index Clustered Index A clustered index defines the order in which data is physically stored in a table. Table data can be sorted in only way, therefore, there can be only one clustered index per table. In SQL Server, the primary key constraint automatically creates a clustered...
Clustered indexes only sort tables. Therefore, they do not consume extra storage. Non-clustered indexes are stored in a separate place from the actual table claiming more storage space. Clustered indexes are faster than non-clustered indexes since they don’t involve any extra lookup step....
Ordered clustered columnstore index An ordered clustered columnstore index (CCI) sorts the existing data in memory before the index builder compresses the data into index segments. This has the potential of more efficient segment elimination, resulting in better performance as the number of segments ...
