The new restrictions were added as part of CASSANDRA-1377 for 0.6.5 and 0.7,
AFAIK it's to ensure the file names created for the CFs can be correctly
parsed. So it's probably not going to change.
The names have to match the \w reg ex class, which includes the
Ah, sorry, I forgot that underscore was part of \w.
That will do the trick for now.
I do not see the big issue with file names though. Why not expand the
allowed characters a bit and escape the file names? Maybe some sort of URL
like escaping.

Juho, do you mind sharing your implementation with the group?
We'd love to help as well with rewriting the thrift interface, specificaly
TSocket.php which seems to be where the majority of the problems are
lurking.
Has anyone tried compiling native thrift support as described here
Chen,
Have you considered using http://www.slideshare.net/otisg/lucandra Lucandra
for Inbox search?
We have a similar setup and are currently looking into using Lucandra over
implementing the searching ourselves with pure Cassandra.

Hi guys,
There are several patches you need to apply to Thrift to completely resolve
all timeout errors.
Here's a list of them along with a link to download a patched thrift
library:

Is it possible this was a new node with a manual token and
autobootstrap turned off?
If not, could you give more details about the node?

Have you considered instead of retrying the failing node, to iterate
through other nodes in your cluster?
If one node is failing (let's assume it's overloaded for a minute),
you're probably going to be better off having the client send the insert

I'm trying to manage my cassandra cluster from a remote box and having issues
getting nodetool to connect. All the machines I'm using are running on AWS.

I think that JMX needs additional ports to function correctly. Try to
disable all firewalls between the client and the server so that client
can connect to any port in the server and try again.

Thanks! That did it. Looks like the connection happens on 10036 and then the
server negotiates a separate port for continued communication.
Found this article once I knew what to look for. It also describes how to get
more consistency on port numbers to allow for ssh tunneling and firewalls.
Is there an easy way to retrieve all values from a CF.. similar to a
dump?
How about retrieving all columns for a particular key?
In the second use case a simple iteration would work using a start and
finish but how would this be accomplished across all keys for a
particular CF when you

We use Lucandra as well for searching for users, as well as
geo-encoding. It really works well except for numeric fields.

That bug may be a bit of an issue, but after they release 0.6.5 all the
Lucene functionality will be available to you.
what's the average size of a user?
As I know, lucandra will first poll the data from cassandra, then do
computation in the client. That's ok for small rows.
But we have 1M row in average, and some rows scale to 100M; at the same
time, we expect high reading qps.
