Communicate to the Individual
I may think I'm trying to reach the crowd, but I'm really trying to reach each person within the crowd. The "crowd" doesn't actually exist.

Comments posted to this topic are about the item SQL Server Columnstore Index Fragmentation
Hi i was surprised to see the approach my coworkers used to sunset talend...
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?
