You experience decreased performance when you stage many records (specifically, more than 1 million records) in Master Data Services (MDS) for Microsoft SQL Server 2012 or SQL Server 2014. The slow performance affects the leaf member staging scenario. Specifically, slw performance affects the udp_name_Leaf stored procedure.
Note In this procedure name, the word "name" is a placeholder for the actual staging table that was specified when the entity was created.
This performance issue occurs when the ImportType=6 parameter is used in the ImportType staging table column that instructs the staging procedures to permanently delete the members that are specified in the staging table from the entity.
This performance issue affects statements against the #TablePR temporary table that is referenced in the udp_name_Leaf stored procedure.
After you apply the fix, a clustered index is added in a stored procedure that is used when you stage data in MDS.
