Push LINQ: Watching Data Fly By
In this session Jon Skeet, author of Manning's C# In Depth, explains the "Push LINQ" framework he developed with Marc Gravell.
The "standard" LINQ to Objects is based on IEnumerable, involving the consumer "pulling" data from a supplier. This works very well in many cases, but has some unfortunate consequences when many consumers are interested in the same data, or when a producer wishes to push data selectively from a single source to different consumers.
Push LINQ is based on observers subscribing to events to see data as it's produced. This enables multiple aggregates to be computed with a single pass through the data, as well as allowing data to be fully streamed in cases which might otherwise require buffering.
Review:
Jon Skeet reveals the Push LINQ framework that he and Marc Gravell have developed to provide a solution for a familiar issue of traversing data stored in a linked list whilst having an efficient implementation for pulling such data without the need for more than one traversal. Jon begins with the explanation of how his framework operates, via user interaction; he provides a solid foundation of understanding for viewers to translate his ideas into the C# code behind the ideas. He outlines the advantages and limitations of his framework, such as allowing multiple aggregates to be computed with single traversals through potentially large amount of streaming data and inability to direct such data to multiple consumers. Although currently Jon and Marc’s framework may appear to have few real world applications, it is certainly very promising - especially if the ability to use multiple consumers is implemented.
