PARTITIONING 03/12/2016 | SQL Saturday #569 - Prague 2016

Partitioning Symptoms? Processing Query Data Management

Partitioning - Processing What to do? Read -> Process -> Write Processing Speed INT or DECIMAL, Yes! Floating Points, No! Increase the amount of memory available for Analysis Services during processing of partitions. Process fewer partitions in parallel. Define smaller partitions. Recommendation: a partition size containing between 5 and 20 million records. Design fewer aggregations for your partition. 03/12/2016 | SQL Saturday #569 - Prague 2016

Partitioning - Processing ProcessFull; ProcessData; ProcessIndex; ProcessClearIndexes; ProcessAdd; ProcessClear; ProcessFull => ProcessClear, ProcessData, and ProcessIndex. Full: deletes existing partition data, indexes, and aggregations and fully reprocesses a partition. Data: deletes existing partition data, indexes, and aggregations and loads only data in a partition. Index: builds indexes and aggregations for a partition. ClearIndexes: deletes partition indexes and aggregations. Add: incrementally updates a partition by adding new data to it. Clear: deletes partition data, indexes, and aggregations.

Partitioning - Processing Partition Processing Load Speed (Rows Read/Sec) 2008: 50K OK, 100K Optimized 2016: 100 OK, 150K Optimized OLE DB for SQL Server over Native Client Increase the network Packet Size from 4096 bytes  to 32 Kbyte (32767). JumboFrames – Network setting Enter the Bios Power options menu and see if you can disable settings like ‘Processor Power Idle state’.  In the Windows Control Panel, set the Server Power Plan to max. throughput

SYNCHRONIZATION 03/12/2016 | SQL Saturday #569 - Prague 2016

Synchronization Why? How? Restore Robocopy Cowboy development Built-in feature

Synchronization What User must be a member of the Analysis Services server administrator role on the Target server. User must have Full Control permissions on the Source database. TCP port 2383 must be open on both servers to allow remote connections between default instances. Both the Source and Target server must be the same version. Edition needs to be either Enterprise, Developer, or Business Intelligence. Server mode must be identical on the two, either Tabular/Tabular or Multidimensional/Multidimensional. 03/12/2016 | SQL Saturday #569 - Prague 2016

Integration TESTING 03/12/2016 | SQL Saturday #569 - Prague 2016

Integration Testing Benefits How? Keep from seeing the same bug over and over again Make sure you don’t break anything else Check for performance degradation How? C#/VB.Net code in Visual Studio (Unit Test Project)

CUSTOM ASSEMBLIES 03/12/2016 | SQL Saturday #569 - Prague 2016

Custom Assemblies When? How? What? Noteable: Security High Cardinality Text Search in several attributes Some NonEmpty scenarios (think T-SQL INNER JOIN) How? C#/VB.NET Assembly integrated with Analysis Services DebugView (SysInternals) https://technet.microsoft.com/en-us/sysinternals/debugview.aspx What? Show me the Money! 1.2M Products and we already see a significant difference Noteable: Security
