I was hoping someone could share their opinions on the following CF designs or
suggest a better way of doing it.
My app is constantly receiving new data that contains URLs. I was
thinking of hashing this URL to form a key. The data is a JSON object with
several properties. For now many of its pr
ut this is also a limitation with the Thrift API -- it's
not CQL specific. It turns out that deleting a slice of columns is
difficult. There's an old JIRA ticket somewhere that describes the
issues.

Looking at the CQL spec, it doesn’t seem to be possible to delete a range of
columns for a given key without specifying the individual columns to be
removed, for e.g.
DELETE col1 .. col20 from CF WHERE KEY=
Am I correct in thinking so or have I missed that somewhere?
For anyone using Codeigniter and interested. I've written a little library
to integrate
Codeigniter with PHPcassa and consequently Cassandra.
It provides you with access to code igniter's $this-db instance that only
has
the library's methods and phpcassa's.

Does anyone have a working 0.7 thrift example in PHP...?
I compiled 0.5 version of thrift and built the PHP bindings
but when I try to run the php example on the wiki I get
TException: Error: Attempt to send non-object type as a T_STRUCT
It may also be an idea to check the node's memory usage. I encountered this on
a few occasions and I simply killed
any unneeded process that was eating away my node's memory. In each instance it
worked fine after there was about 300MB of free memory

Is it possible to get the first x columns from a row without knowing the
column names?
So far i've been working with just grabbing all the columns in a row or just
getting a specific column that i know the name of.
If it is possible, can anyone point me in the right direction of how to do
this?
ion he was saying that if its a normal
row i.e not Super, there is a limit but if the said row is within a structure
of type Super then there is a potentially unbounded
amount of columns to be had.
Is my original understanding correct, have i just misinterpreted his article?

Courtney
I haven't looked at your previos e-mail( s) or the responses to them but have a
look at
http://prettyprint.me/2010/02/14/running-cassandra-as-an-embedded-service/
the post was written by one of the guys who maintains the hector cassandra
client.
In any case the simple and short answer is yes, h
any presentation or the
like where its mentioned so I can get a better idea of what its for.
