Contributor Checklist

Format the title according to the contribution guidelines
Assign the type: and (comp: or inst:) labels in addition to any other useful labels
Avoid using close, fix, or any linking keywords when referencing an issue
Use solves instead, and assign the PR milestone to the issue
Update the CODEOWNERS file on source file addition, migration, or deletion
Update public documentation with any new configuration flags or behaviors

Jira ticket: [PROJ-IDENT]

Note: Once your PR is ready to merge, add it to the merge queue by commenting /merge. /merge -c cancels the queue request. /merge -f --reason "reason" skips all merge queue checks; please use this judiciously, as some checks do not run at the PR-level. For more information, see this doc.

Nice, I did the same (chunked transfer encoding) in dd-trace-go

Avoids a fleet of apps starting at the same time from exporting OTLP metrics in sync

❔ question: ‏Instead of implementing two encoding for the OtlpGrpcRequestBody payload, what about using the OkHttpUtils.gzippedRequestBodyOf() decorator instead for the gzip part? That would keep it simpler and help with later http component refactoring.

❔ question: ‏Instead of implementing two encoding for the OtlpGrpcRequestBody payload, what about using the OkHttpUtils.gzippedRequestBodyOf() decorator instead for the gzip part? That would keep it simpler and help with later http component refactoring.

Unfortunately we can't use the gzippedRequestBodyOf decorator as-is for GRPC because it gzips the entire decorated request - whereas for GRPC we need to first gzip the payload completely and then add some control bytes in order to get the final request.

This means for gzipped GRPC we would need 3 request instances:

a request holding the original payload
the wrapper created by gzippedRequestBodyOf around the first request
another request wrapper to add the GRPC compressed control bytes

and we can't write the GRPC control bytes until we've gzipped the payload to see how long it is, as the length of the gzipped data is part of those control bytes...

That doesn't mean that we couldn't improve reusability of these components though in the future...
