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
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

I m currently using the the datastax opscenter.
How do we add column to the column families in opscenter??
As far as I'm aware of that is not possible using the opscenter.
I recommend you use the cassandra-cli and perform an update column family
query.

Can this be set on a CF basis.
Only this CF needs higher consistency level.

Only this CF needs higher consistency level.
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 level
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.

To be clear, the incompatibility we've talked about does *not* concern
any of the 1.0 releases (you'll want to refer NEWS file for any
details on the upgrade path for these versions).
The incompatibility here is only between 1.1.0-beta1 and 1.1.0-beta2.

If you are running a multi datacenter setup, you should upgrade to
the latest 1.0.x (or 0.8.x) release before upgrading. Versions
There is no such thing as pure insert which will give an error if the thing
already exists. Everything is really UPDATE OR INSERT. Whether you say
UPDATE, or INSERT, it will all act like UPDATE OR INSERT, if the thing is
there it get over written, if it isn't there it gets inserted.
Got it. Moving the packages I use to another repo now.

What I want to tell was this driver does not use INSERT key word. Since
CQL support for using INSERT keyword and it is more generic key word used
to add new records, it's more user friendly to use INSERT key word to add
new record set rather using UPDATE keyword.

Hello everyone,
How are people running multi DC Cassandra across remote locations? Are
VPNs used? Or some dedicated application proxis? What is the norm here?
Any advice is much appreciated,
Alex
We built multi-DC right from the start -- two equal locations about 1000 miles
apart but on the same provider backbone so there was reasonably robust and
consistent connectivity between them. We did this using software ipsec to set
up tunnels between the private networks in each location, but
Hello,
I am planning on testing OpsCenter to see how it can monitor a multi DC
cluster. There are 2 DCs each on a different side of a firewall. I've
configured NAT on the firewall to allow the communication between all
Cassandra nodes on ports 7000, 7199 and 9160. The cluster works fine.
However
hey all,
I have a new cassandra node that I've setup so that I can get better
acquainted with this technology. Thus far I've been using the
cassandra-cli and it'd been a fun experience so far. However I know
that there are a few cassandra gui's out there and I was just
wondering which ones

No vpn for us. We do it all over pure ipv6
The best would to not use update / insert at all but set / put / save.

Datastax OpsCenter really is pretty awesome. I haven't tried anything
else, but have had no issues with opscenter.

Just so you know. OpsCenter is a good tool for managing your cluster
and viewing data in your keyspaces/columnfamilies (data besides string
data currently doesn't display an extremely user friendly way, it will
display hex). Currently you can not insert data to your cluster using
the OpsCenter gui
Cool guys, thanks. I'll certainly give it a try now that my cassandra
setup is functioning well. But what about the Apollo gui for
Cassandra. Has anyone else had any experience with that and maybe know
if it supports entering data into the cluster?

This setup may be possible although there are a few potential issues.
Firstly, see:

61621 by default (those can be configured though). The

1.0.0 does not generate cross-dc forwarding message at all, so you're
safe on that side.

There's nothing that will do it automatically. You need to increment it
yourself.

Hi,
yes you can insert data into cassandra with apollo, just try the demo
center: http://www.codefreun.de/apolloUI/
You can login by just press the login-button (autologin) and play around
with it.
More info: http://codefreun.de/en/apollo-en
If you miss any feature, please let me know!
