hi,
look at the collection type support in cql3,
e.g
http://www.datastax.com/documentation/cql/3.0/cql/cql_using/use_list_t.html
we can append or remove using "+" and "-" operator
UPDATE users
SET top_places = top_places + [ 'mordor' ] WHERE user_id = 'frodo';
UPDATE users
SET top_places = t
Is there a reason you can't use:
DELETE FROM table_name WHERE s = ? AND p = ? AND o = ? AND c = ?;

Also I don't think you can null out columns that are part of the primary
key after they've been set.

Setting the columns to null is essentially deleting them from my
understanding. A delete operation works on the entire row.

Hi,
I'm using a Cassandra table to store some data. I created the table like
this:
CREATE TABLE IF NOT EXISTS table_name (s
The new node has managed to stay up without dying for about 24 hours now...
but it still is in JOINING state. A new concern has popped up. Disk usage
is at 500GB on the new node. The three original nodes have about 40GB each.
Any ideas why this is happening?

Dear All,
We have a requirement to store 'N' columns of an entity in a CF. Mostly this is
write once and read many times. What is the best way to store the data?
Composite CF
Simple CF with value as protobuf extracted data
Both provides extendable columns which is a requirement for our usage.
