Event Store Persistent Subscriptions

One of the really nice features of Event Store is the Persistent Subscriptions that were implemented in v3.2.0.  I was previously using catch-up subscriptions but needed the ability to have many worker processes handle events from the same stream. First lets take a look at couple of the subscription models Event Store suports. Catch Up Subscriptions As mentioned, I previously would use catch-up subscriptions for various use cases.  One of them would be for sending emails on specific events occurring in the system. A worker process would subscribe to the $all event stream and handle incoming messages accordingly. The issue is that catch… Read More »Event Store Persistent Subscriptions

At first I was just going to generate some random data and serialize it at runtime but then I found Mockaroo, which provided a small dataset of random data that I could download. So now that I had this generated file, I  wanted to include the file in my project as an embedded resource in which would be read and at returned as output. If you have any questions, please follow me… Read More »ASP.NET Core Embedded Resource

Gzip Compression with NancyFX

I was looking at the size of the payloads in my web api and thought it would be worth investigating if adding HTTP compression via gzip would be worthwhile.

Compressing I’ve basically taken Simon’s code and added it to a new class that implements IApplicationStartup. There are a few checks that occur before compressing the output. Does the incoming request accept header contain gzip? Is the outgoing HTTP… Read More »Gzip Compression with NancyFX
