I think this is useful for the reasons I wrote about in the code comment.
However it does come at a performance cost - there is now one extra allocation per incoming message batch. (just for the vec, the
Message
s themselves do not allocate)I still think its worth it though.
An easy way to test this new handling is to run a shotover config without a database running at the destination address.
