Azure Stream Analytics

2. The traditional data warehouse

3. Modern data warehouse

4. What are customers wanting to do?

5. Canonical scenarios for real-time processing

6. KUKA Systems Group created an IoT-powered plant that
centrally connects and monitors hundreds of robots.

7. Introducing Azure Stream Analytics

9. Procure HW Infrastructure and setup
Code for ingress, processing and egress
Plan for resiliency, such as HW failures
Design solution
Build Monitoring and Troubleshooting

11. • Built-in monitoring
– View your system’s performance
at a glance
– Help you find the cost-optimal
way of deployment

12. 3 lines of code in Stream Analytics
Thousand lines of code in other solutions
• Only SQL queries needed
– Developers uses declarative
SQL commands
– Some functions take several
lines of code versus thousands
from other solutions

13. • Implement temporal functions
• Manage out-of-order events
• Manage actions on late events

14. End-to-end stream processing architecture

ReferenceData - Commercial vehicle registration data

17. Application Components
Components of an Azure Stream Analytics Application
Azure SQL DB
Azure Event Hubs
Azure Blob StorageAzure Blob Storage
Azure Event Hubs
Reference Data
Query runs continuously against incoming stream of events
Events
Have a defined schema and
are temporal (sequenced in
time)

18. Temporal Windows
• Tumbling Windows
– Repeating, non-overlapping, fixed interval windows
• Hopping Windows
– Generic window, overlapping, fixed size
• Sliding Windows
– Slides by an epsilon and produces output at the occurrence of an event

19. Tumbling Window
SELECT System.TimeStamp AS OutTime, TollId,
COUNT (*)
FROM Input TIMESTAMP BY EntryTime
GROUP BY TollId, TumblingWindow(minute,5)

20. Hopping Windows
SELECT System.TimeStamp AS OutTime, TollId,
COUNT (*)
FROM Input TIMESTAMP BY EntryTime
GROUP BY TollId, HoppingWindow(minute, 10 , 5)

21. Sliding Windows
SELECT System.TimeStamp AS OutTime, TollId, COUNT (*)
FROM Input TIMESTAMP BY EntryTime
GROUP BY TollId, SlidingWindow(minute, 3)
HAVING Count(*) > 3
Finds all toll booths which have served more than 3 vehicle in the last 3 minutes
