8. Lap Around SQL Azure

9. SQL Azure Network Topology Application Load Balancer TDS (tcp:1433) Applications use standard SQL client libraries: ODBC, ADO.Net, … Load balancer forwards ‘sticky’ sessions to TDS protocol tier Data Node Gateway Scalability and Availability: Fabric, Failover, Replication and Load balancing

10. Tools SQL Server Management Studio 2008 R2 (SSMS) DB Design Web/Silverlight Interface - Project Houston https://www.sqlazurelabs.com/houston.aspx https://www.sqlazurelabs.com/houston.aspx SQLCMD 3 rd Party tools Most 3 rd Party tools for SQL Server work with SQL Azure

11. Connection Management Connections may drop due to: Network connectivity blips Idle or long running transactions Idle > 30 minutes Long running transactions > 30 minutes Throttling (taking too many resources) Measured by IO load and CPU utilization Database failover activity Machine failure: automatic recovery Load balancing used to ensure ‘resource fairness’ DOS protection may deny connectivity: If too many failed connection attempts are made The servers running your databases are not impacted by such attacks

12. Limitations (1) Maximum DB Size 50GB Consider Sharding SQL Server Agent Mail Full Text Search Filestream Unsupported T-SQL, DMV, System Objects. See BOL Profiler

13. Limitations (2) Backup/Restore as we know it (CREATE DATABASE … AS COPY OF) Analysis Services Reporting Services

14. Error Messages http://technet.microsoft.com/en- us/library/ff394106.aspx Error Codes 40000-41000 +Reason Codes for Throttling

15. Maintenance DBA is Database Administrator, no longer Server and Installation guy DB Design Index Maintenance DB copies Consultant to the business

16. No Maintenance = ExtraCost DB space allocated is billed for Fragmentation = space allocated Fragmentation = CHF CHF CHF (or $ $ $) Re-Index is important ALTER INDEX ON REBUILD WITH (ONLINE=ON) Example: Before: 32 594MB (31.83GB) After: 26 406MB (25.78GB)

17. Migration to SQL Azure

18. What works just out of the box? Application Data Access TierJust WorksYour Mileage May Vary Data Access APIs Support ADO.Net, ODBC, EF and PHP OleDB Security Model SQL AuthWindows Auth Connection Management Apps with transaction retry logic, 3-tiered, stateless or partially statefull apps Legacy Apps 2 tiered apps with online connections Admin and Programmability Surface Support Tables, Views, Sprocs, Functions, Triggers, built-in data types etc Server level options, FTS, Service Broker, Distributed Transactions Collation Behavior Apps explicit with collation options apps depending on special db/server collation defaults

19. SQL Azure Migration Tool http://sqlazuremw.codeplex.com/ Scenario: Migration of schema and/or data with fine grain control. Pros SQL Azure Compatibility Analysis Uses high performance APIs SMO and BCP Built in retry and chunking First try clustered index creation Create batch scripts (great for Test & QA) Cons BCP data stored on local file system Not a full SQL Engine TSQL Parser NOT Supported by Microsoft

20. Management Studio – Generate Script Wizard Scenario: Migration of schema and/or data with fine grain control Pros Native support for SQL Azure Schema options: “Engine Type = SQL Azure” Ensures correct options and settings are applied for the TSQL script generation Requires explicit action on unsupported objects. Cons Verbose – INSERT Statements instead of raw data Data is scripted with a fixed 100 row batch size. Edit “GO” statements between small batches Round-trip Efficiency Use “SET NOCOUNT ON”

21. DAC (Data-tier Application) Packages Scenario: Self contained package for moving schema easily through the development lifecycle Pros SQL Azure Object compatibility Analysis Deployment via Management Studio Supports DB lifecycle Cons No Data Scripting, only schema

22. Use the right tools for data movement BCP & Bulk Copy APIs Scenario: High speed programmable data import and export Best Practices Optimize Databases for Data Import Disable/Delay creation of Non-Clustered Indexes Order Data on the Clustered Index Disable Triggers and Constraint checking -N Native mode so no data type conversion needed. -c Character mode for interoperability -b batchsize will let you control transaction size -h”TABLOCK, ORDER(…)” optimize writes

23. Use the right tools for data movement SSIS – Best of Breed Data Transformation Utility Scenario: Design Surface – Data Flow Tasks Diverse Source and destinations To/From Flat Files, ADO.Net, OleDB Fully programmable flow Loops, Sorts, Conditional operators, XML/WebServices Processing etc VS Debugging support with data viewers, watches and conditional breakpoints Best Practices Remember; Optimize Databases for Data Import Disable/Delay creation of non-Clustered Indexes Order Data on the Clustered Index Disable Triggers and Constraint checking Batch Size: Adjust the transaction size Buffer and Blob temp storage area; spread over to multiple drives for large data transfers Parallelization – based on execution trees, task will auto parallelize
