+#### Trace Flag: 11024
+Function: In Microsoft SQL Server 2017, when incremental statistics are built on the top of partitioned tables, the sum of modification counts of all partitions is stored as the modification count of the root node.
+When the modification count of the root node exceeds a threshold, the auto update of statistics is triggered.
+However, if the modification count of any single partition does not exceed the local threshold, the statistics are not updated.
+Additionally, the modification count of the root node is reset to zero. This may cause delay in the auto update of incremental statistics.
+When trace flag 11024 is enabled, the modification count of the root node is kept as the sum of modification counts of all partitions.<br />
