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

What is the difference between calling *writer.addColumn()* on the column's
name and value, and

shouldn't be the fault of the Murmur3 partitioner which guarantees a
uniform distribution of keys across token-ranges according to the doc. )
