+ System performance. System core performance review, redesign of system core related to routing and content streaming -### Technical info -In version [22.0](https://github.com/ThreeMammals/Ocelot/releases/tag/22.0.0), the bug was found in the explicit default constructor of the [FileQoSOptions](https://github.com/ThreeMammals/Ocelot/blob/main/src/Ocelot/Configuration/File/FileQoSOptions.cs) class with a maximum [TimeoutValue](https://github.com/ThreeMammals/Ocelot/blob/main/src/Ocelot/Configuration/File/FileQoSOptions.cs#L9). Previously, the default constructor was implicit with the default assignment of zero `0` to all `int` properties. + - Modification of the `RequestMapper` with a brand new `StreamHttpContent` class, in `Ocelot.Request.Mapper` namespace. The request body is no longer copied when it is handled by the API gateway, avoiding Out-of-Memory issues in pods/containers. This significantly reduces the gateway's memory consumption, and allows you to transfer content larger than 2 GB in streaming scenarios. + - Introduction of a new Message Invoker pool, in `Ocelot.Requester` namespace. We have replaced the [HttpClient](https://learn.microsoft.com/en-us/dotnet/api/system.net.http.httpclient) class with [HttpMessageInvoker](https://learn.microsoft.com/en-us/dotnet/api/system.net.http.httpmessageinvoker), which is the base class for `HttpClient`. The overall logic for managing the pool has been simplified, resulting in a reduction in the number of CPU cycles. + - Full HTTP content buffering is deactivated, resulting in a 50% reduction in memory consumption and a performance improvement of around 10%. Content is no longer copied on the API gateway, avoiding Out-of-Memory issues. + - **TODO** Include screenshots from Production... +
-The new explicit default constructor breaks the old implementation of [QoS TimeoutValue](https://github.com/ThreeMammals/Ocelot/blob/main/src/Ocelot/Requester/HttpClientBuilder.cs#L53-L55) logic, as our [QoS documentation](https://ocelot.readthedocs.io/en/latest/features/qualityofservice.html#quality-of-service:~:text=If%20you%20do%20not%20add%20a%20QoS%20section%2C%20QoS%20will%20not%20be%20used%2C%20however%20Ocelot%20will%20default%20to%20a%2090%20seconds%20timeout%20on%20all%20downstream%20requests.) states: -![image](https://github.com/ThreeMammals/Ocelot/assets/12430413/2c6b2cd3-e1c6-4510-9e46-883468c140ec)

+ +### Roadmap +We would like to share our team's plans for the future regarding: development trends, ideas, community expectations, etc. +- **Code Review and Performance Improvements**. Without a doubt, we care about code quality every day, following best development practices. And we review, test, refactor, and redesign features with overall performance in mind. In the next few releases (versions 23.x-24.0) we will take care of: generic providers, multiplexing middleware (Aggregation feature), memory management. +- **Server-Sent Events protocol support**. There is a lot of community interest in this HTTP-based protocol. +- **Long Polling for Consul provider**. [Consul](https://www.consul.io/) is our leading technology for service discovery. We are constantly improving the use cases for the `Ocelot.Provider.Consul` package and trying to improve the code inside the package. +- **QoS feature refactoring**. [Polly](https://github.com/App-vNext/Polly/) was released with the new v.8.2+ after .NET 8. So we have to update `Ocelot.Provider.Polly` package taking into account new Polly behavior of redesigned features. +- **Brainstorming** to redesign Rate Limiting, Websockets. More details in future release notes. +- **Planning** of support for Swagger and gRPC proto.
