StreamInsight V2.1

To demonstrate the new APIs in StreamInsight V2.1, we have created the StreamInsight Product Team Samples V2.1 that co-exist with the samples for previous versions (V2.0 and below).

Application Purpose
HelloWorld Simple StreamInsight application to get started.
ComposingQueries Shows how to compose queries in comparison with the same application in the V2.0 sample set.
ComposingQueriesNoAdapter Same as above, but using .Net sequence integration instead of adapters.
Checkpointing Shows how to take checkpoints and recover from interruptions.
Hitchhiker_V21 Accompanies the updated version of the Hitchhiker's Guide to StreamInsight Queries.
UdsoPatternDetector Demonstrates how to use a User-defined StreamOperator (UDSO) to implement a complex pattern detection scenario.
WCF Shows how to send and receive events via WCF.

StreamInsight V2.0

The Microsoft StreamInsight Product Team Samples V2.0 are demonstrating key aspects of the StreamInsight CEP platform. The purpose of the samples is to provide a guide through the StreamInsight development experience, demonstrating common design patterns for adapters, queries, and applications. The emphasis is on the teaching character, not on feature completeness, performance, or robustness. Follow the product team on Twitter for latest updates.

The samples consist of a set of Visual Studio Solutions, each of which contains at least one input adapter, one output adapter, and one main application. Each adapter is a separate projects and can be included in multiple solutions.

Adapter Purpose Teaching Value VS Version
DataGenerator (IA) Generates events with random payload values Event push model (through a callback); simple implementation of the adapter state diagram 2008
OutputTracer (OA) Traces output events on the console or a file Simple untyped output adapter design; useful for prototyping and testing 2008
SimpleTextFileReader (IA) Reads lines from a csv file and transforms them into events Simple untyped input adapter 2008
SimpleTextFileWriter (OA) Writes events as lines to a file in csv format Simple untyped output adapter 2008
WcfAdapter (IA, OA) Reads and writes events from and to ECF endpoints Simple remoting of event streams 2008
AsyncCsv (IA, OA) Reads (asynchronously) and writes events from and to csv files Using IO completion for efficient file reading; using an adapter class abstraction for point/interval/edge 2008
SQL (IA, OA) Reads and writes events from and to SQL Server tables Using a SqlDataReader to interface with SQL; Writing an untyped adapter 2008

Application Purpose Teaching Value VS Version
ComposingQueries Applies two subsequent queries to data from the DataGenerator and dumps the result on the console Use dynamic query composition to stream into two output adapters 2008
TrafficJoinQuery Reads and processes traffic data from two text files Use the explicit query binder model; join two input streams 2008
WcfApplication Applies a query to an event stream from a WCF endpoint Demonstrates the usage of the WCF adapters with a simple query 2008
PatternDetector Uses a user-defined operator to implement a pattern matcher on csv input data Implementing a state machine through the extensibility framework 2008
Hitchhiker Contains the sample queries used in the "Hitchhiker's Guide" paper Various query patterns 2008
SequenceIntegration Hitchhiker queries; Performance Counter import; Northwind DB temporal queries Shows how to use .NET sequences to use files, perf counters, OData feeds as event sources, and WPF elements as event sinks 2010
SqlApplication Applies a temporal query against SQL input data Demonstrates the usage of the SQL adapters with a simple query 2008

The samples are complete, the .csv files are in the folder of the project using the adapters, because the actual data belongs to the scenario, not to the adapters. You can find them in Applications/TrafficJoinQuery.

could someone post the sample .csv files and such so that the samples are complete....they are nowhere to be found in the downlad. would be nice to have when looking at it.

Each sample project contains a README with some further information. Please let us know if you have further questions!

Do you have any explaination document about the sample code?
