4. Traditional ETL Process
• Extract data from different sources
• different source systems
• different data organization and/or format
• (non-)relational databases, flat files
• Transforms it to fit operational needs
•
•
•
•
•
Translating coded values
Encoding free-form values
Deriving a new calculated value
Aggregation
data profiling, data quality
• Loads it into the end target
• database, data mart, data warehouse

7. Traditional ETL Process (Microsoft Glasses)
• Control Flow
• implement repeating workflows
• Connecting containers and tasks into an
ordered control flow by using precedence
constraints
• controlling external processes
• load meta objects and data container
• prepare data files

8. Traditional ETL Process (Microsoft Glasses)
• Data Flow
• Adding one or more sources to extract data
from files and databases
• Adding the transformations that meet the
business requirements
• Adding one or more destinations to load data
into data stores such as files and databases
• Configuring error outputs on components to
handle problems

9. Microsoft Big Data Solution

10. Challenges of Big Data
• large amounts of data from multiple sources
• the volume of this amount of data goes into the terabytes,
petabytes and exabytes
• Classic relational database systems as well as statistical and
visualization programs are often not able to handle such large
amounts of data
• according to calculations from the year 2011, the global volume
of data doubles every 2 years

11. Challenges of unstructured data
• does not have a pre-defined data model or is not organized in a predefined manner
• typically text-heavy, but may contain data such as dates, numbers,
and facts as well
• structure, while not formally defined, can still be implied
• aggregates can not be accessed with computer programs through a
single interface
• Emails, audio - and video files without tags, also contributions in
different media such as online forums or on social-media platforms

15. Useful Apache Hadoop Components (for ETL)
Apache Flume
Apache Sqoop
• Stream data from multiple sources into
Hadoop for analysis
• Allows data imports from external datastores
and enterprise data warehouses into Hadoop
• a large scale log aggregation framework
• Parallelizes data transfer for fast performance
and optimal system utilization
• Collect high-volume Web logs in real time
• Insulate themselves from transient spikes when
the rate of incoming data exceeds the rate at
which data can be written to the destination
• Guarantee data delivery
• Scale horizontally to handle additional data
volume
• Copies data quickly from external systems to
Hadoop
• Makes data analysis more efficient
• Mitigates excessive loads to external systems

16. Useful Apache Hadoop Components (for ETL)
Apache Hive
Apache Pig
• data warehouse infrastructure built on top of
Hadoop
• Platform for cerating MapReduce programs
• supports analysis of large datasets stored in
Hadoop's HDFS
• SQL-like language called HiveQL
• Internally a compiler translates HiveQL
statements into a directed acyclic graph of
MapReduce jobs
• Language is called Pig Latin
• abstracts Java MapReduce Job to something
similar to SQL
• Can use User Defined Functions written in Java,
Python, JavaScript, Ruby or Groovy
• Pig uses ETL

17. Useful Apache Hadoop Components (for ETL)
ODBC/JDBC Connectors
Apache Storm
• Microsoft® Hive ODBC Driver
• distributed real-time computation system for
processing fast, large streams of data
• processing one million 100 byte messages per
second per node
• Scalable with parallel calculations that run
across a cluster of machines
• Fault-tolerant – when workers die, Storm will
automatically restart them. If a node dies, the
worker will be restarted on another node
• Storm guarantees that each unit of data (tuple)
will be processed at least once or exactly once.
http://www.microsoft.com/en-us/download/details.aspx?id=40886
• Original: Apache Hive ODBC Driver provided
by Simba
• transforms an application’s SQL query into the
equivalent form in HiveQL
• Supports all major on-premise and cloud
Hadoop / Hive distributions
• Supports data types: TinyInt, SmallInt, Int,
BigInt, Float, Double, Boolean, String, Decimal
and TimeStamp

18. Some statements to be clarified...
• Hadoop will steal work from ETL solutions
• ETL is running faster on Hadoop
• Hadoop is not a data integration tool
• Hadoop is a batch processing system and Hadoop jobs tend to
have high latency
• Data integration solutions do not run natively in Hadoop
• Elephants do not live isolated
• Hadoop is not a solution for data quality (and other specialized
Transformations)

20. SSIS – not just a simple ETL Tool

21. Use SQL Server Integration Services to…
•
•
•
•
•
•
build complex workflows
manage Windows Azure and HDInsight clusters
load data into HDInsight/HDFS
control jobs on HDInsight
get data from Hive, Pig, …
combine Hadoop with „traditional“ ETL

22. Tools to work with HDInsight
• SSIS Tasks for HDInsight
