Availability zones are analogous to racks not data centres . EC2 regions
are equivalent to data centres.
You can use vnodes if you want to deploy a cluster across multiple regions
(data centres) with one availability zone per region. Each region maintains
a separate ring.
I don't know if you can
Hey guys,
False alarm, sorry about that. Our column-names are byte-concatenations of
short integers and we had been constructing the column names wrongly before
attempting a delete. We fixed the problem and we've been able to delete the
columns without issue.

Thanks for the reply. I have one more question. If multiple columns with
identical names but with different timestamps are bulk loaded (with
sstableloader) into a CF, and we had LCS running in the background, would a
slice predicate query retrieve multiple columns with the same name assuming
compac
es not have a TTL.

Let's say I've initialized a *SSTableSimpleWriter* instance and a new
column with TTL set :
*SSTableSimpleWriter writer = new SSTableSimpleWriter( ... /* params here
*/);*
*Column column;*
What is the difference between calling *writer.addColumn()* on the column's
name and value, and *writer.addE
curs. ( it
shouldn't be the fault of the Murmur3 partitioner which guarantees a
uniform distribution of keys across token-ranges according to the doc. )

We ran nodetool repair on all nodes for all Keyspaces / CFs, restarted
cassandra and this is what we get for nodetool status :
bin/nodetool -h localhost status

We have set up a 24 node (m1.xlarge nodes, 1.7 TB per node) cassandra
cluster on Amazon EC2 :
version=1.2.9
replication factor = 2
snitch=EC2Snitch
placement_strategy=NetworkTopologyStrategy (with 12 nodes each in 2
availability zones)
Background on our use-case :
We plan on using hadoop with ss
