The difference between libraries and frameworks

  • Article

The concept behind frameworks and libraries is to provide reusable code that you can use to perform everyday tasks so that developers don’t have to write all of the code from scratch for every project.

Self-Service Databases

Question of the Day

SQL Server Columnstore Index Fragmentation

The columnstore index is absolutely different than the traditional rowstore b-tree index. Because of this, it doesn't suffer from the same kind of fragmentation across pages as the b-tree index. Yet, it does suffer from a type of fragmentation brought about by an excess of deleted rows in a rowgroup and a lack of compression of storage because more things are in the delta store. While b-tree indexes use dm_db_index_physical_stats to show fragmentation, which system tables or DMVs can be used in SQL Server (prior to SQL Server 2025) to determine columnstore fragmentation?
