Agenda

• Overview








• Summary

11


• Innovative new technology for analytical queries– Columnar storage

– New run-time engine with vector (aka SIMD) processing, deep multi-core optimizations and cache-aware memory management

– “Active compression” - unique encoding for further storage reduction beyond DB2 10 levels, and run-time processing without decompression

• “Revolution by Evolution”– Built directly into the DB2 kernel

– BLU tables can coexist with traditional row tables, in same schema, tablespaces, bufferpools

– Query any combination of BLU or row data

– Memory and CPU cache optimized

• Value: Order-of-magnitude benefits in ….– Performance

– Storage savings

– Time to Value

DB2 V11.1 BLU Load Optimization

• SAP R3load parameter “OPT_COMPRESS” uses new CLI LOAD

attribute RESETDICTIONARYONLY

• RESETDICTIONARYONLY option is used to create a BLU compression

dictionary from sample data without loading any data.

• Advantages

Higher compression ratio with better BLU table dictionaries

No (large) temporary files on the database server are created any more.

14


Push Down BW Query Processing to DB2 BLU (1)Push down of cell restrictions in SAP BW queries

• Individual filter conditions for key figures and characteristics

• Often used in BW queries

• Complex Customer reports may contain 100s of cell restrictions

Available with SAP BW 7.50 SP4 on DB2 V11.1 and V10.5

15







16







17


Processing without push down of cell restrictions

• Large result set is transferred to SAP BW application server

• Final result is aggregated on SAP BW application server

Processing WITH push down of cell restrictions to DB2 BLU

• Restricted key figures are aggregated in DB2 BLU engine

• Small result set is transferred to SAP BW application server.

• No or significant less aggregation on SAP BW application server

Significant reduced data processing on the SAP BW application server

Up to large factor faster BW queries

BLU Acceleration: MPP (Massive Parallel Processing) Scale Out

Technology

– Pervasive SMP & MPP Query Parallelism

– Each table has its onw distribution key defined

– Each table uses a common data compresion dictionary

across all db partitions

– Data exchange during distributed joins and aggregation

processing occurs entirely within the BLU runtime in

native columnar format (avoids conversion to row format)

Value Proposition

– Improve Response Time

• All servers contribute to the processing of a query

– Massively Scale Data

• Significantly beyond current practical limits

– Streamline BLU Adoption

• Add BLU Acceleration to existing data warehouses

DB2 V11.1 – BLU MPP Support for SAP BW

BLU MPP for large SAP BW customers

• Allows Horizontal Scalability

• Consider BLU MPP usage for large BW databases

with > 70 TByte uncompressed data;

this equates to > 10 TByte BLU compressed data

• Database Partition size:

At a minimum, all CPUs and memory of one

socket

As a rule of thumb, 16 GByte memory per core

• Same table distribution as on row- store (DPF)

Master Data and Dimension tables on Part. 0

(Administration Partition)

Small PSA, DSO and Fact tables on Partition 0

(Administration Partition)

Large PSA, DSO and Fact tables are

SAP BW Query Performance Tests with BLU MPP• Runtime comparison of BW InfoCube queries: Single Member versus MPP

• Single Member configuration: All tables are located on single member database

• MPP configuration: Fact tables are distributed on 2 database partitions

• Result: Average query run time on MPP system is factor 1.86x faster on MPP

A Paradigm Change in SAP Application Programming

Data-To-Code:Intensive computations

in APPLICATIONlayer

Code-To-Data:Intensive

computations

in DATABASE layer

From Classic Approach

• Avoid costly computation on database level

• Transfer data to application server and compute there

To Data Centric Approach

•Get the algorithm to the data

•Only transfer computation results to the application server

24


SAP Core Data Services (CDS)Next generation data definition and access for database centric applications CDS presents the data layer in SAP’s modern business solution

Defines business objects as database views that contain SQL functions

Flexible and powerful data modelling with huge variety of options and functions

CDS Views are modelled with ABAP Eclipse Editor
