[Question] Encrypt attributes in all spans

[dwelias]

I am looking to encrypt certain attribute values in the spans going out to Phoenix. I don’t have the ability to run a collector so am trying to do it on the client side.

So far I have created a filter span per the [https://arize.com/docs/phoenix/tracing/how-to-tracing/advanced/modifying-spans ]documentation. I then encrypted the attributes I needed but cannot update the span as it’s a readonly so I created a new span using tracer.start_span which seemed to work but it broke the trace as each span now shows up as a separate trace.

Should I be using tracer.start_as_current_span?

Is this the right approach or are there any other options?

@dwelias even though the spans are marked as read-only you should be able to modify them in the span processors or exporters. Hope that helps.

Unf the span is readonly, I was able to make a copy of the span but it wasn’t complete so it broke the trace relationships.
