Radim Kolar commented on CASSANDRA-3910:
----------------------------------------
With FD 9, there is situation when Cassandra considers other node as UP (which
really is) but network connection between nodes is too slow (most messages sent
between nodes timeouts withing 30 sec timeout limit) just occasional
message/cluster heartbeat passes.
In that kind of situation is better to break cluster. Nodes do not need to wait
for each other and work separated (app can survive that) and use HH after
network condition (DDOS) improves.
Node in not viable cluster consume lot of memory because many messages are
waiting to be sent and there is possibility to OOM or deadlock.

> I would like to have phi_convict_threshold floating point number instead of
> integer. Value 8 is too low for me and value 9 is too high. With converting
> to floating point, it can be better fine tuned.
