The reason why these lob activities are in the output, is that SQL Server uses its native lob storage engine for the storage of the columnstore segments. There is also an additional cache for columnstore segments in SQL Server’s main memory, that is separate from the buffer pool. The rowstore index show significant more reads. Since the columnstore index was first introduced back with SQL Server® 2012, there have been a lot of questions about when you should use a columnstore and when you should use a traditional rowstore index. This is especially true following Microsoft’s latest enhancements to the columnstore. Microsoft touts some impressive performance gains using the columnstore … The reason why these lob activities are in the output is that SQL Server uses its native lob storage engine for the storage of the columnstore segments.
