Gzip OTLP/JSON request bodies

[mwear]

As discussed at the SIG meeting earlier today, we can improve the performance of our collector exporter by using gzip compression on request bodies.

I would be interested in taking this up. @mwear Can you please point me where I can start looking for this?

I did take a look at the XHR and Fetch instrumentation, and I didn't find any request body attribute being added to the span. I think I might be missing something here

Or, did you mean the service request sent by the collector exporter?

opentelemetry-js/packages/opentelemetry-exporter-collector/src/platform/browser/CollectorExporterBrowserBase.ts

Line 69 in 62f8695

const serviceRequest = this.convert(items);

Seems like the efforts for this is stopped. May I work on this?
