Summary of changes

Tags that are readonly should be implemented as such, and return a value directly

Reason for change

We have some tags that currently always return the same value, but are implemented as writeable fields. This requires a backing field, and so means the object is sliiiightly more allocatey than it needs to be.

Implementation details

Switch to using => readonly properties instead of { get; set; }

Test coverage

If the tests pass, it's fine

Comparison explanation

Execution-time benchmarks measure the whole time it takes to execute a program, and are intended to measure the one-off costs. Cases where the execution time results for the PR are worse than latest master results are highlighted in **red**. The following thresholds were used for comparing the execution times:

  • Welch test with statistical test for significance of 5%
  • Only results indicating a difference greater than 5% and 5 ms are considered.

Note that these results are based on a single point-in-time result for each branch. For full results, see the dashboard.

Graphs show the p99 interval based on the mean and StdDev of the test run, as well as the mean value of the run (shown as a diamond below the graph).

Probably more than you wanted to do this PR, but I was looking into why we can't do the same with MessagingSystem, and noticed that AzureServiceBusTags inherits that property from OpenTelemetryTags, but I don't think AzureServiceBusTags needs to inherit from OpenTelemetryTags anymore now that the Service Bus integration uses call-target instrumentation instead of the OpenTelemetry observer.

Maybe something @pablomartinezbernardo can look into later.

Yeah, I was going to take a look at this, but given our lack of extensive ServiceBus testing, I was a little hesitant, so will move to a separate PR

Actually, as far as I can tell, we still have an OpenTelemetry observer? 🤔

I don't know if we still use the observer. Question for Pablo 😅
