In this step by step video we build 2 simple .NET 6 Services and work with the Polly library to ensure we can handle any transient faults that may occur when one service calls the other.
The video includes:
• Overview of transient faults
• A look at the Retry Policy
• Step by Step Service build with .NET 6 & C#
• Implementing immediate, liner and exponential back off retry policies
• Working with the HttpClient and HttpClientFactory
• HttpClient & HttpClientFactory

Thanks. This was a very helpful video, and it was quite timely that I came across it, as I’ve been looking for a good way to handle throttling in a way I can easily adjust. One of the PaaS whose API I use on a daily basis tightened their throttling and I started getting massive amounts of 429:Too Many Requests errors. This whole month has been fixing those

32min before actually beginning to use polly, just to write 7 line of code ? past you prepared code and do a 30sec explanation on theses and go straight to the point... go slow after that, but really... take some inspirations from Nick Chapsas work for example.

And Why the Polly is using _clientPolicy.ImmediateHttpRetry.ExecuteAsync Asyncronous function instead of being just Synchronous
@IldarIsm
@IldarIsm 2 жыл бұрын
because http call is asyncronous in nature. it sent request, the thread returned to the pool and cpu core process something else. when the response come the network driver initiate interupt call.OS will ask another thread get the task and process response bytes.
