[jira] [Created] (ARROW-7516) [C#] .NET Benchmarks are broken

Eric Erhardt created ARROW-7516:
-----------------------------------

             Summary: [C#] .NET Benchmarks are broken
                 Key: ARROW-7516
                 URL: https://issues.apache.org/jira/browse/ARROW-7516
             Project: Apache Arrow
          Issue Type: Bug
          Components: C#
            Reporter: Eric Erhardt


See [https://github.com/apache/arrow/pull/6030#issuecomment-571877721]

 

It looks like the issue is that in the Benchmarks, `Length` is specified as `1_000_000`, and there has only been ~730,000 days since `DateTime.Min`, so this line fails:

https://github.com/apache/arrow/blob/4634c89fc77f70fb5b5d035d6172263a4604da82/csharp/test/Apache.Arrow.Tests/TestData.cs#L130

A simple fix would be to cap what we pass into `AddDays` to some number like `100_000`, or so.
