NCache For Pub/Sub Messaging Cache

NCache provides a Pub/Sub messaging paradigm to publish or subscribe messages. It is responsible for exchanging messages between multiple applications where the publisher sends the messages without knowing who the subscriber(s) is. The channel used for the exchange of messages is called Topic and the subscriber subscribes to their topic of interest for receiving the relevant messages. NCache provides multiple types of subscriptions between the subscribers and publishers.

Threadpool Setting for .NET 8.0

• For Windows, it is essential to set the UseWindowsThreadPool flag to true. For already built applications, set the UseWindowsThreadPool flag in runtimeconfig.json file:

  {
    "runtimeOptions": {
       "configProperties": {
          "System.Threading.ThreadPool.UseWindowsThreadPool": true
       }
    }
  }
  

  During development phase, this file will be overwritten with each compilation. Therefore, define the UseWindowsThreadPool property in the project file instead, as follows:

  <Project Sdk="Microsoft.NET.Sdk">
  
   <PropertyGroup>
     <UseWindowsThreadPool>true</UseWindowsThreadPool>
   </PropertyGroup>
  
  </Project>

• For Linux, it is mandatory to set the MinimumThreads flag to a value of 100 in the runtimeconfig.json, as follows:

  {
     "runtimeOptions": {
        "configProperties": {
           "System.Threading.ThreadPool.MinThreads": 100
        }
     }
  }
