Inter-node messaging is rewritten using Netty in 4.0. It will be better to

Hello,
I just saw this message still has no response.
Do we have any inbuilt features to log slow\resource heavy queries?
I think we don't have this in Cassandra yet. I also believe it's in DSE, if
it's something you'd really need :).
I tried to check data in system_traces.sessions to check c
Hello,
It's hard to say what the best configuration is.
*max_hints_delivery_threads*: I think it's said you should use 2 delivery
thread per DC (as a starting point).
*max_hint_window_in_ms:* depends on your need (and what the cluster can
bear of course). Generally, the default of 3 hours is use
Hello LAD,
I do not know much about the SSTable Loader. I carefully stayed away from
it so far :). But it seems it's using thrift to talk to Cassandra.

bootstrap. For C*2.1, nothing equivalent sadly. Thus old school technics
apply and the possible alternatives are
Option 1 - safe and slow- Stop Cassandra from the stuck joining node.

This isn’t true. Aside from when using the default superuser, only
CRM::getAllRoles reads at QUORUM (because the resultset would include the
