<p>Do I understand correctly, that they spent memory storing largish N hash values per server, so that request hash  determines which server to send request to using closest higher value of all server hashes?<p>That in effect boils down to consistently selecting server S with probability P, where P is function of weight and total number of servers?<p>Surely there must be better way to select server with a given probability without storing a massive lookup table of hashes? Randevouz hashing of some sorts</p>

<p>>  a sequential scan may push ~100GB of other data from memory (shared buffers or page cache).<p>Small note, if I remember correctly PostgreSQL allocates small buffer within shared_buffers for bulk reads. It is so that single sequential scan won't flush all of shared buffers content.<p>Similar mechanism exists for a pagecache implementation on Linux. It is divided into generations based on access patterns.</p>

<p>Nice writeup, but I don't understand how `curl` didn't trigger bug for them (or any other hyper HTTP server out there), given the explanation in the article.<p>`curl --http1.1` sends `Connection: Close` so sender (hyper) must attempt to shutdown connection after sending whole body. Surely any network is slower than memory copy into socket kernel buffers, so it must reliably trigger condition "buffer flush can't be done in one go" and thus trigger early TCP shutdown.</p>
