Multiple DC is usually useful in case u need Geo Redundancy or have distributed
workload. Do u have these clusters at same physical location? If 3 nodes are at
diff locations dont u need geo red for disaster ? Whats ur RF for cf?

I would like do live migration instead of offline bulk load.
You can make 3-node old cluster as dc1, the 5-node new cluster as dc2,
then nodetool rebuild dc1 on dc2, in this way, you don't need to take
down the cluster to maintain consistency.

Hi,
Does Apache Cassandra (not DSE) support Hive Integration?
I found couple of open source efforts but nothing is available currently.
Thanks

Hello,
I am unable to connect to the nodes of our second datacenter, not even from
localhost.

Connection error: ('Unable to connect to any servers', {'...':
OperationTimedOut('errors=None, last_host=None',)})
I already checked some things:

Hi All,
We have a cassandra cluster of 3 machines, which has a table containing 50
millions of rows. We are making a new cluster of 5 nodes and we want to
migrate this table to the new cluster.
Please suggest what would be the best and least time taking process. I know
we can use sstable
Hi,
tl;dr : How to choose between having a Cluster with 2 DC and having 2
separate clusters as follow:
cluster_name: mycluster
KS1 {DC1: 3, DC2: 0} and KS2 {DC1: 0, DC2: 3}
OR
cluster_name: cluster1
KS1 {DC: 3}
+
cluster_name: cluster2
KS2 {DC: 3}
We can use distinct columns and row to keep
