I do not think you want to std::move here. factory may be called multiple times, once for each ordering key that is discovered (dynamically). You want a copy, and note that they are captured by copy too.

This is called at most once, and therefore a std::move(topic) was appropriate.

I am beginning to think this is too clever for its own good.
Maybe we should do this (starting around line 133):
auto cp = background->cq();
auto sink = DefaultBatchSink::Create(stub, cq, std::move(retry_policy), std::move(backoff_policy));
auto connection = RejectsWithOrderingKey::Create(BatchingPublisherConnection::Create(topic, options, {}, sink, cq);
if (options.message_ordering()) {
auto factory = [topic, options, sink, cq](std::string const& key) {
return BatchingPublisherConnection::Create(topic, options, key, SequentialBatchSink(std::move(sink), std::move(cq)));
};
connection = OrderKeyPublisherConnection(std::move(factory));
}It makes a few more copies than it should, but it is probably more readable. Alternatively, moving the lambda to a function may make it more obvious. Your call.

I think the code is fine. I like that BatchingPublisherConnection::Create() is only called once

we
std::move(options)in themake_connectionlambda which captures by reference. Then we keep usingoptions...I am not sure how to test for this change.
