You set the consistency with every request.
Usually a client library will let you set a default one for all write/read
requests.
I don't know if Hector lets you set a default consistency level per CF.
Take a look at the Hector docs or ask it in the Hector mailing list.

The consistency level of read/write operations is specified at each
single read/write function call. This means that you have to use the
desired consistency leve
Can this be set on a CF basis.
Only this CF needs higher consistency level.

Like everything else in Cassandra, If you need full consistency you need to
make sure that you have the right combination of (write consistency level)
+ (read consistency level)
if
W = write consistency level
R = read consistency level
N = replication factor
then
W + R > N

Hi!
Asking again, as I didn't get responses :)
I have a ring with 3 nodes and replication factor of 2.
I have counter cf with the following definition:
CREATE COLUMN FAMILY tk_counters
with comparator = 'UTF8Type'
and default_validation_class = 'CounterColumnType'
and key_validation_c
Thanks for the clarification,

That's right - you can have many threads incrementing the same counter
and it's safe. But reading and increment

No,
Cassandra doesn't support atomic counters. IIRC it is on the list of things
for 1.2.

Hi
Hi!
Is there a way to read and increment counter column atomically, something
like incrementAndGet (Hector)?

Not anytime soon. We're busy launching a bunch of stuff (some of which
