Hi All,
The question is really simple. Is there anyone out there using a set of
scripts in production that detects failures of cassandra processes and
restarts them or takes required actions.
If so, how can we implement a generic solution for this problem?

Hello,
We have a ring of 12 nodes with 6 in one data center and 6 in another.
We want to shutdown all 6 nodes in data center 1 in order to close
it down. We are using a replication factor of 3 and are using
RackAwareStrategy with version 0.6.6.
Are there any best practices for doing this type
Point releases,7.0 to 7.1, are normally in place upgrades one node at a time.
The cluster will remain online at all times.
AFAIK major version upgrades would normally allow for in place upgrade,
supporting a mixed environment during the change over. If the on disk format
changed there may be a

Have you considered using Solr / lucene for the search? It has a lot more
search features, and it really good at faceted navigation through a product
catalogue. It sounds like it would be a better fit for this task.
You can build facets for your price ranges, do the product name thing and
Hi there,
How do I set an index on a column in cassandra 0.7?
This is what I am trying to do:
[defa...@keyspace1] get Standard1 where user = 'jpartogi';
No indexed columns present in index clause with operator EQ
I can not find this in the CLI help nor the wiki. Maybe I am not looking
hard
It's part of update column family:
[defa...@unknown] help update column family;
...
- column_metadata: Metadata which describes columns of column family.
Supported format is [{ k:v, k:v, ... }, { ... }, ...]
Valid attributes: column_name, validation_class (see comparator),
0.6-0.7 will require a full cluster restart.
0.7-0.8 will require a rolling restart, so long as CASSANDRA-1015 is completed.
keyspace/cf definitions will be readable across major versions, or
there will be a way provided to migrate them if that is not possible.
Gary.

Hi All,
After installing 0.7RC1 RPM on CentOS and starting the cassandra service I am

Is this a known issue? Any recommendations?

They should be set in cassandra-env.sh. Did you build the rpm yourself using
the spec file in the source? If so its probably a bug. If not where did you
get the rpm file from?

My schema has a row that has thousands of Super Columns. The size of each

Hi,
as I got answered on my mail, secondary indexes for super column families is
not supported yet, so you have to implement your own
easy way: keep another column family where the row key is the value of your
field and the columns are the row keys of your super column family
(inverted index)
actually, the solution would be something like my last mail, but pointing to
the name of the super column and the row key

You can use column and super column names with the get_slice() function without 0.7 secondary indexes. I'm assuming that the original query was to test for the existence of a column by name.In the case below, to retrieve the full super column would require to request...First to test the condition.

Thanks Aaron!
The first request requires you to know the SuperColumn name. In my case I
don't know the SuperColumn name cause if I know then I can read the super
column. I need to find the SuperColumn that has column with given value for
a given column.
The usecase is that application allows
