This perl library has been extremely useful for scripting up data migrations. I
wonder if anyone knows of the easiest way to use lists with this driver?
Throwing a perl array in as a parameter doesn’t work as is:
my $q = $cass->prepare("update contact set name=?, address=? where
uuid=?")->g
I'm trying to get CQL going for my CentOS 5 cassandra PHP platform. I've
installed thrift, but when I try to make cassandra-pdo or YACassandraPDO
for that matter, none of the tests pass. And when I install it with PHP,
phpinfo still doesn't show it loading and it doesn't work.
Any ideas would be
has there been any thought about adding cell-level security to Cassandra ?
something similar to:

Hello Clint
The Resolution status of the JIRA is set to "Later", probably the
implementation is not done yet. The JIRA was opened to discuss about impl
strategy but nothing has been coded so far I guess.

Folks,
Does anyone know how I can modify multiple rows at once in a
lightweight transaction in CQL3?

You might want to use the Priam tool for backups.

If you don't want to use Priam, you should read this Datastax entry on
backup and restore.

I'm wanting to back up my data to amazon S3. Can anyone please tell about
which directories should I copy to the remote location for backup so as to
restore the entire Cassandra data in the event of any failures?

I'm with you Ed.
I love that Cassandra is moving forward at a very fast pace, but often I
get the impression some people want to avoid thrift at all cost whether it
makes sense or not. I totally understand the commiters don't have enough
bandwidth to make sure all existing cases transition smoothl
The main issue is that cassandra has two of everything. Two access apis,
two meta data systems, and two groups of users.
Those groups of users using the original systems thrift, cfmetadata, and

Hi,
I'm getting a "TSocket read 0 bytes" error in cqlsh when doing a "SELECT *
FROM tbl".
Anyone else experienced this?
It's a single node cluster running locally. I've tried doing a nodetool
cleanup but that didn't solve the issue.

What happens if a ParNew is triggered while CMS is running? Will it wait
