Data Warehouse vs Data Lake
@ITCAMPRO #ITCAMP18Community Conference for IT Professionals
Azure Data Lake
• Comprehensive, big-data storage + analytics platform
• Purpose-built from real-world experiences
– Office 365, Skype, Bing, etc.
• Leverage existing skills and technologies
• Benefits of an Azure-hosted service
– Elastic, dynamically provisioned compute resources for varying query needs
– Infinite storage capacity
– Focus on extracting meaning from data, not on infrastructure
@ITCAMPRO #ITCAMP18Community Conference for IT Professionals
Azure Ecosystem Integration
@ITCAMPRO #ITCAMP18Community Conference for IT Professionals
But what is Data Lake in fact
• A repository for analyzing large quantities of disparate sources of data
in its native format
• One architectural platform to house all types of data:
– Machine-generated data (ex: IoT, logs)
– Human-generated data (ex: tweets, e-mail)
– Traditional operational data (ex: sales, inventory)
@ITCAMPRO #ITCAMP18Community Conference for IT Professionals
Data Warehouse vs Data Lake
@ITCAMPRO #ITCAMP18Community Conference for IT Professionals
Data Lake use case
• Staging for the Data Warehouse
• So called Active Archiving
–You can run queries against historical data, too
–It will be federated query to access historical and current
data
–The data is stored for the indefinite time
@ITCAMPRO #ITCAMP18Community Conference for IT Professionals
Data Lake use case
• An external system loads data to the Data Lake
• The data is analyzed case by case. Processing is highly
parallel
–Schema on read – we read all the data to determine the
value of the data
• Deliver the data once the requirements are fully
known
–Data warehouse – schema on write
–Data Virtualization
@ITCAMPRO #ITCAMP18Community Conference for IT Professionals
U-SQL
• Based on SQL and C#
– C# expressions and types
– Tables, views, window functions, etc.
– User-defined functions/operators/aggregators in C#
• Typical job
1. Read data from file/table/federated source
2. Transform rowset in a pipeline
3. Output rowset to table (INSERT) or file
@ITCAMPRO #ITCAMP18Community Conference for IT Professionals
U-SQL - extensibility
• C# expressions
• UDF’s – functions
• UDAGG’s – aggregates
• UDO’s - operators
@ITCAMPRO #ITCAMP18Community Conference for IT Professionals
UDO’s - operators
• Extractors  EXTRACT
• Outputters  OUTPUT
• Processors PROCESS
• Appliers  PROCESS
• Combiners  COMBINE
• Reducers REDUCE
@ITCAMPRO #ITCAMP18Community Conference for IT Professionals
UDO’s – extractor & outputter
• User-defined extractors
–Extract row by row
–Used to implement data extraction from custom structured
files
• User-defined outputters
–Output row by row
–Used to output custom data types or custom file formats
@ITCAMPRO #ITCAMP18Community Conference for IT Professionals
UDO’s – processor & applier
• User-defined processors
–Take one row and produce one row
–Used to reduce the number of columns or produce new
columns with values that are derived from an existing
column set
• User-defined appliers
–Take one row and produce 0 to n rows
–Used with OUTER/CROSS APPLY
@ITCAMPRO #ITCAMP18Community Conference for IT Professionals
UDO’s – combiner & reducer
• User-defined combiners
–Combines rowsets--user-defined JOINs
• User-defined reducers
–Take n rows and produce one row
–Used to reduce the number of rows
@ITCAMPRO #ITCAMP18Community Conference for IT Professionals
What else can you do?
• JSON
• R
• Python
• Cognitive Services
@ITCAMPRO #ITCAMP18Community Conference for IT Professionals
USQL & Cognitive
• Imaging: Detect faces
• Imaging: Detect emotion
• Imaging: Detect objects (tagging)
• Imaging: OCR (optical character recognition)
• Text: Key Phrase Extraction
• Text: Sentiment Analysis
•

  • 2. @ITCAMPRO #ITCAMP18Community Conference for IT Professionals Many thanks to our sponsors & partners! GOLD SILVER PARTNERS PLATINUM POWERED BY

  • 5. @ITCAMPRO #ITCAMP18Community Conference for IT Professionals And now…
  • 6. @ITCAMPRO #ITCAMP18Community Conference for IT Professionals Data Warehouse vs Data Lake
  • 7. @ITCAMPRO #ITCAMP18Community Conference for IT Professionals Azure Data Lake • Comprehensive, big-data storage + analytics platform • Purpose-built from real-world experiences – Office 365, Skype, Bing, etc. • Leverage existing skills and technologies • Benefits of an Azure-hosted service – Elastic, dynamically provisioned compute resources for varying query needs – Infinite storage capacity – Focus on extracting meaning from data, not on infrastructure
  • 8. @ITCAMPRO #ITCAMP18Community Conference for IT Professionals Azure Ecosystem Integration
  • 9. @ITCAMPRO #ITCAMP18Community Conference for IT Professionals But what is Data Lake in fact • A repository for analyzing large quantities of disparate sources of data in its native format • One architectural platform to house all types of data: – Machine-generated data (ex: IoT, logs) – Human-generated data (ex: tweets, e-mail) – Traditional operational data (ex: sales, inventory)
  • 10. @ITCAMPRO #ITCAMP18Community Conference for IT Professionals Data Warehouse vs Data Lake
  • 11. @ITCAMPRO #ITCAMP18Community Conference for IT Professionals Data Lake use case • Staging for the Data Warehouse • So called Active Archiving –You can run queries against historical data, too –It will be federated query to access historical and current data –The data is stored for the indefinite time
  • 12. @ITCAMPRO #ITCAMP18Community Conference for IT Professionals Data Lake use case • An external system loads data to the Data Lake • The data is analyzed case by case. Processing is highly parallel –Schema on read – we read all the data to determine the value of the data • Deliver the data once the requirements are fully known –Data warehouse – schema on write –Data Virtualization
  • 13. @ITCAMPRO #ITCAMP18Community Conference for IT Professionals U-SQL • Based on SQL and C# – C# expressions and types – Tables, views, window functions, etc. – User-defined functions/operators/aggregators in C# • Typical job 1. Read data from file/table/federated source 2. Transform rowset in a pipeline 3. Output rowset to table (INSERT) or file
  • 14. @ITCAMPRO #ITCAMP18Community Conference for IT Professionals U-SQL - extensibility • C# expressions • UDF’s – functions • UDAGG’s – aggregates • UDO’s - operators
  • 15. @ITCAMPRO #ITCAMP18Community Conference for IT Professionals UDO’s - operators • Extractors  EXTRACT • Outputters  OUTPUT • Processors PROCESS • Appliers  PROCESS • Combiners  COMBINE • Reducers REDUCE
  • 16. @ITCAMPRO #ITCAMP18Community Conference for IT Professionals UDO’s – extractor & outputter • User-defined extractors –Extract row by row –Used to implement data extraction from custom structured files • User-defined outputters –Output row by row –Used to output custom data types or custom file formats
  • 17. @ITCAMPRO #ITCAMP18Community Conference for IT Professionals UDO’s – processor & applier • User-defined processors –Take one row and produce one row –Used to reduce the number of columns or produce new columns with values that are derived from an existing column set • User-defined appliers –Take one row and produce 0 to n rows –Used with OUTER/CROSS APPLY
  • 18. @ITCAMPRO #ITCAMP18Community Conference for IT Professionals UDO’s – combiner & reducer • User-defined combiners –Combines rowsets--user-defined JOINs • User-defined reducers –Take n rows and produce one row –Used to reduce the number of rows
  • 19. @ITCAMPRO #ITCAMP18Community Conference for IT Professionals What else can you do? • JSON • R • Python • Cognitive Services
  • 20. @ITCAMPRO #ITCAMP18Community Conference for IT Professionals USQL & Cognitive • Imaging: Detect faces • Imaging: Detect emotion • Imaging: Detect objects (tagging) • Imaging: OCR (optical character recognition) • Text: Key Phrase Extraction • Text: Sentiment Analysis •
  • 21. @ITCAMPRO #ITCAMP18Community Conference for IT Professionals No more slides. Never
  • 22. @ITCAMPRO #ITCAMP18Community Conference for IT Professionals Thank you!
