             Summary: Async support for C# 
                 Key: AVRO-3831
                 URL: https://issues.apache.org/jira/browse/AVRO-3831
             Project: Apache Avro
          Issue Type: Improvement
          Components: csharp
            Reporter: Avi Levin


De/serialization libraries in .NET are expected to support asynchrony for reasons well-described for example [here|https://learn.microsoft.com/en-us/aspnet/core/fundamentals/best-practices?view=aspnetcore-8.0#avoid-blocking-calls]:
{quote}Asynchronous APIs allow a small pool of threads to handle thousands of concurrent requests by not waiting on blocking calls. Rather than waiting on a long-running synchronous task to complete, the thread can work on another request [...] Many synchronous blocking calls lead to Thread Pool starvation and degraded response times.
{quote}
The first step would be to add async equivalents to each method in the {{Encoder}} and {{Decoder}} implementations, using the async methods in {{Stream}} for its implementation. (There is a "[flag-argument hack|https://stackoverflow.com/a/54267939/1180926]" pattern used in many libraries, including the Azure SDK, to prevent code duplication between the sync and async copies of otherwise identical methods.)

Upstream libraries like {{DataFileReader/DataFileWriter}} can be updated once the en/decoders have been.



AVRO-2252 requested this, but as far as I can tell it never got backlogged in any of the issues mentioned there.
