XC 9.2.0 introduced the RebuildDescendants task which will call the Sitecore.Data.SqlServer.SqlServerDataProvider.RebuildDescendants() method.
The Descendants table stores "ancestors-descendants" relations between items and is sed by FastQuery functionality (Sitecore.Data.DataProviders.Sql.FastQuery).
The query executed by the RebuildDescendants has been added as part of building the XcMssql target.
