Hi,
let's say i have 5 nodes a DC the dynamic snitch scores are
A => '1.84106731901363'
B => '1.1386762906094'
C => '2.63620400428772',
D => '3.06495631470972',
E => '0',
Badness_threshold is set to 1,
Does this mean th
cluster is back to
1 datacenter with 3 nodes and then add them sequentially again making sure
the configuration in the Snitch is the proper one.

I was thinking of leveraging ec2 snitch. But my question is then how do I
give replica placement options?
Or can I give snitch as ec2snitch and write the nodes
cassandra-topology.prop and in give locator strategy at time of creating
keyspace as network topology strategy. But will it work?
And
Seems like a more robust solution would be to implement
dynamic-snitch-like behavior in the client. Hector has done this for
a few months now.

Hi all!
Assuming a node ends up in GC land for a while, there is a good chance that
even though it performs terribly and the dynamic snitching will help you to

Also during startup the snitch will log what it was able to read so you can
check it is read what you think.
I there is a problem with the topology that would probably explain the other

If that does not fix it can you provide the keyspace
I guess otherwise it NPEs?

Hi all
after upgrading to 0.7 we have a small problem with dynamic snitch:
we have rf=3, quorum read/write and read repair prop set to 0. Thus cassandra
always shortcuts reads to only 2 hosts.
Problem is that one of our nodes get ignored unless using a little patch and

As far as I understand it the MessagingService is always user in the strong

MessageDeliveryTask will still be used which in turn calls the
