Ariel Weisberg commented on CASSANDRA-9237:
-------------------------------------------
One of my get out of jail free ideas was to use SCTP on the large message
connection. Large messages might not notice any overhead from SCTP. SCTP and
the implementation in OpenJDK is kind of an unknown though. SCTP allegedly
handles head of line blocking issues.
Disadvantage is that I don't see a way to upgrade a connection to SCTP after
the fact, it would require an additional listening port, and it doesn't have an
old IO implementation.
