1. 1 Advanced Topics Using Microsoft SQL Server 2005 Integration Services Allan Mitchell – SQLBits – Oct 2007

2. 2 Introduction Loading SSAS partitions directly Using an SSIS Package as a data source Data Mining in your Packages Understanding Performance Q and A

3. 3 Who am I? SQL Server MVP Co author on Wrox book on SSIS www.SQLDTS.com, www.SQLIS.comwww.SQLDTS.comwww.SQLIS.com Consultancy company – Konesans (www.konesans.com)

4. 4 What I will not cover Finding SSIS Creating packages General package design

5. 5 Loading SSAS Directly Dimension And Partition Processing –Do not need to load the underlying DB –Quicker ROI –Don’t fully process the Partition/Dimension outside of the ETL process !

6. 6 DEMO

7. 7 Using SSIS as a data source SSRS –Complex logic (Microsoft.SqlServer.Dts.DtsClient) Windows App –Populate a web page perhaps Custom Component –Take the output of one package and use it in another

8. 8 DEMO

9. 9 Data Mining in SSIS Transforms –Data Mining Query Insurance Company perhaps –Term Extraction Textual Extraction (DT_WSTR or DT_NTEXT) –Term lookup Textual Lookup (DT_WSTR or DT_NTEXT) Destinations –Data Mining Model training

10. 10 DEMO

11. 11 Performance Tuning Data Correlation Use a merge Join over lookup – why? Remember sorted inputs – Do on source preferably. Avoid delay between 2 sources hitting.

12. 12 Performance Tuning Buffer Strategy DefaultMaxBufferRows (10000) DefaultMaxBufferSize (10 MB) MaxBufferSize and MinBufferSize (100MB and 64KB) Avoid many small buffers. Turn on logging of BufferSizeTuning event

13. 13 Parallel Load (Try 1)

14. 14 Parallel Load (Try 2)

15. 15 Parallel Load (Try 3)

16. 16 The Raw File Only SSIS can read and write Only Adapter that does not use a Connection Manager High Speed Source and Destination No datatype conversions required Eases back pressure

17. 17 Demo The Raw File and How To Read

18. 18 Access Modes and OLEDB Source Adapter Do not use Table or View as Access Mode Use SQL Command instead Openrowset (Overhead + bad exec plan) Sp_prepare (much better) (MS say 17* improvement)
