After reading this I dont see why I should change that assumption?  I have to rebuild connections occasionally but its never cost my application so much that an alternative more complicated abstraction layer made sense.
I usually write req&amp;#x2F;response over tcp, an even more inaccurate abstraction. Occasionally nonblocking code. Never have I wanted more complexity than nio in my application layer.&lt;p&gt;Devs do know that &amp;quot;tcp is not a stream of bytes&amp;quot; but deliberately do not want to get app code involved.</text><parent_chain></parent_chain></comment><story><title>TCP is an underspecified two-node consensus algorithm</title><url>https://morsmachine.dk/tcp-consensus</url></story>
