Is your feature request related to a problem? Please describe.

We compare spans which have unique attribute values (such as UUIDs). This creates issues when comparing two sets of spans.

Describe the solution you'd like

We want to ignore a specific span attribute value during comparison.

Describe alternatives you've considered

We use this code for now:

func ignoreSpanAttribute(attributeName string, traces ptrace.Traces) {
	for i := 0; i < traces.ResourceSpans().Len(); i++ {
		rs := traces.ResourceSpans().At(i)
		for j := 0; j < rs.ScopeSpans().Len(); j++ {
			ss := rs.ScopeSpans().At(j)
			for k := 0; k < ss.Spans().Len(); k++ {
				span := ss.Spans().At(k)
				if _, ok := span.Attributes().Get(attributeName); ok {
					span.Attributes().PutStr(attributeName, "*")
				}
			}
		}
	}
}
