I recently attended an excellent free developer conference called DDD11 and went to Joel Hammond-Turner’s session on Splunk. I know our infrastructure team uses Splunk at work and I knew its a powerful framework, although I was really impressed with what it offers… and all for free!
Threading in RX is usually performed by a set of classes called Schedulers, that implement the IScheduler interface. I have interviewed a fair few people who don’t fully understand what thread they are on at various points in the pipeline, especially when we throw in a few ObserveOn and SubscribeOn calls.
What is Replay?
We have been using RX for some time now although we still get caught out on the intricate details. Replay is an extremely useful caching mechanism that allows streams to replay previous entries for new subscriptions, based on count, time or a mixture of both.
Under the covers it’s a multicast with a replay subject:
Observable.Multicast<TSource, TSource>(source, new ReplaySubject(bufferSize))
