In [!INCLUDE[ssSQL15](../../includes/sssql15-md.md)], when a columnstore index is reorganized, there is new functionality to automatically merge any small compressed rowgroups into larger compressed rowgroups, as well as recompressing any rowgroups that have a large number of deleted rows.<br /><br />**Note:** Trace flag 10204 does not apply to columnstore indexes which are created on memory-optimized tables.<br /><br />**Scope**: global or session|
