JON SKEET: PUSH LINQ: WATCHING DATA FLY BY.
n 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.
