> Reporter: Benjamin Mahler
> Labels: performance, tech-debt
>
> Currently, all protobuf message handlers must take a {{vector}} for repeated
> fields, rather than a {{RepeatedPtrField}}.
> This requires that a copy be performed of the repeated field's entries (see
> [here|https://github.com/apache/mesos/blob/9228ebc239dac42825390bebc72053dbf3ae7b09/3rdparty/libprocess/include/process/protobuf.hpp#L78-L87]),
> which can be very expensive in some cases. We should avoid requiring this
> expense on the callers.
