Torsten Grabs Lead Program Manager

2. What’s new in streaminsight for SQL 2012
Microsoft SQL Server 2012 includes the latest version of StreamInsight
StreamInsight is Microsoft’s platform for continuous event-driven processing
Resiliency to outages
Checkpoint recovery
Development experience
User-defined extensions for prediction and pattern matching
LINQ improvements
Embracing .NET 4.0 as the default
Manageability
Performance counters
Administrative events in Windows Event Log
Improved latency

3. Resiliency to outages

4. Resiliency Goal: make StreamInsight applications highly available
Planned downtime
Unplanned outages
Timeliness: recover from outages quickly
Goal is simple: as fast as possible
StreamInsight doesn’t store event data, but it does store query state
Query states can get large
Query state can build up over along time and be hard to recreate
StreamInsight offers different levels of protection that you can choose from depending on your needs

5. Resiliency: Levels of protection
Choose which level of resiliency you need:
Exact equivalence
The same stream of events, regardless of outage
Equivalent events
No missed events, and no wrong events, but duplicates are allowed
State retention
Don’t lose expensive-to-create state
No further guarantees

6. Checkpointing saves a query’s state to disk
What is Checkpointing?
Checkpointing saves a query’s state to disk
You control when the checkpoint is initiated
SI takes care of saving out consistent state
After an outage, StreamInsight can restore this state
This limits state loss during an outage, speeding recovery
Level of correctness depends on additional work we are able to perform
Recovery process is coordinated by SI
With checkpointing, interruptions in the output can still occur during the downtime period

7. Developer experience

8. More Complex Event Processing
Predictive models for e.g. trends or extrapolation
Time
now
Pattern matching

9. More Complex Event Processing
What people want to do
How: New User-Defined Stream Operator
Predictive models
Denial-of-service attacks
Bottleneck prediction
Equipment outages
Online user behavior
Power grid stability
Pattern matching
Fraud detection
Cheat detection
User-defined operator that can be injected in any stream
Stateful computations: you can now retain state between operator invocations
Arbitrary temporal ranges of interest: you can manage your own windows

10. Improved Developer experience
Support for nested type structures
C# classes that nest other C# classes can now be StreamInsight event types
StreamInsight transparently does the mapping to its internal flat event representation
Primitive payloads: now supported
Constant payloads: now supported
Many limitations in LINQ addressed
Multiple JOIN and FROM clauses per statement now supported
Richer support for projection expressions
Support for macros
Expressions with multiple aggregates supported
LET clause supported
