Josh McKenzie commented on CASSANDRA-17768:
-------------------------------------------
Chatting w/Mick offline about this. I'm a little concerned about folks running
in environments w/insufficient or weird TCP_KEEPALIVE that might not realize it
until they upgrade to 4.1 and start having streams / channels that get killed
for inactivity.
While it's certainly redundant in a world w/expected tcp env, and less of a
concern on a single channel vs. the older paradigm, what's the downside to us
reinstating the {{KeepAliveTask}} scheduling code from 4.0 in 4.1 defaulted to
on? I have to assume the volume of messaging from this would be negligible and
historically channels getting closed for inactivity has been a niggling
annoyance for us, so a little redundancy in this area of our communications
would be welcome IMO.
