inconsistencies for the cluster as you are allowing reads to be performed
on a node with token ranges assigned, but no data.

Have you looked at tuning connection pool?

It's still not recommended to start at the same time. Stagger by 2 minutes
is what the following documentation suggests; along with additional steps.

Right! Another reason why I just stick with sequential decommissions. Maybe
someone here could shed some light on what happens under the covers if
parallel decommissions are kicked off.

Are you using vnodes? I typically do one-by-one as the decommission will
create additional load/network activity streaming data to the other nodes
as the token ranges are reassigned.

Did you look at the logs on the source DC as well? How big is the dataset?

What version are you running? Do you see any errors in the system.log
(SocketTimeout, for instance)?
And what values do you have for the following in cassandra.yaml:
- - stream_throughput_outbound_megabits_per_sec
- - compaction_throughput_mb_per_sec
- - streaming_socket_timeout_in_ms

g the cache validity timeframe, future requests for ANY user
stored in the cache do not require a lookup against system_auth. After the
cache validity runs out, any new requests will require a lookup against

If i start the agent on the cluster with encryption, I see lots of these
messages in the C* logs -
Unexpected exception during request; channel
io.netty.handler.ssl.NotSslRecordException: not an SSL/TLS record
And get an error connecting to the cluster from opscenterd.

I have OpsCenter 6.0.7 setup managing multiple clusters. Only one of those
clusters has encryption turned on (both node-to-node and client-to-node).
In order to manage that cluster through OpsCenter, do all subsequent
clusters have to have encryption turned on?
