This is a huge PR that does not touch any of the critical logic "marshaling/unmarshaling" of the pdata. We have e2e tests with the go official generated protobufs to ensure nothing breaks. The easy way to review this is to only look at what change publicly in "pdata/pcommon", "pdata/plog", "pdata/ptrace", "pdata/pmetric", "pdata/pprofile", "pdata/xpdata". This PR also switches the xpada request to use the same generating mechanism as pdatagen. **Binary size before:** ``` 42246018 bin/otelcorecol_darwin_arm64 ``` **Binary size after:** ``` 40709202 bin/otelcorecol_darwin_arm64 ``` Signed-off-by: Bogdan Drutu <[email protected]>
