node.js library?
Hey folks, so I have been noodling on using node.js as a new front end for
the system I built for doing real time aggregate metrics within our
distributed systems.
Does anyone have experience or background story on this lib?
http://code.google.com/a/apache-extras.org/p/cassandra-node/ it seems to be
the most up to date one supporting CQL only (which should not be an issue)
but was not sure if it is maintained or what the background story is on it
and such?
Any other experiences/horror stories/over the rainbow type stories with
node.js & C* would be nice to hear.

As far as I know its the library that was developed by "rackspace".
See
https://github.com/racker/node-cassandra-client
As rackspace is using node.js + cassandra I would expect it works ;)

This is quite a different subject and the question has already been asked a
few days ago (December, 1) :
http://www.mail-archive.com/user@cassandra.apache.org/msg19083.html
Anyways, you can test it by yourself changing the name of the column
family. I don't know more about it by myself.

RE: Schematool

Hi,
I have a keyspace called Index.
I am trying to create it when I create a new cluster from the script that
was created on the old cluster.
create keyspace Index
with placement_strategy = 'SimpleStrategy'
and strategy_options = {replication_factor : 3
and durable_writes = true;
I get an error
[default@City] create keyspace Index
... with placement_strategy = 'SimpleStrategy'
... and strategy_options = {replication_factor : 3}
... and durable_writes = true;
Syntax error at position 16: mismatched input 'Index' expecting set null
My question is
Is Index a reserved word?
How can I create this keyspace? I tried 'Index' and "Index" but I still get
the error and I am not able to create it.
Thanks
Michael

You should be able to use the CLI "show schema yourkeyspace" if your
cassandra is recent enough ( >= 0.8 if I remember well. I think it is better
if you are in 0.8.7 because this command was fixed a couple of times in 8.6
and 8.7).
You can put the "show schema" command into a file and call it with :
"cassandra-cli -h yourhost -f yourfile > 20111208schema" then open your
output file and remove the 2 or 3 useless lines that are written before
"create yourkeyspace".
Hope this will be helpful.

Hi,
Since schematool has been removed from Cassandra is there a way to extract
the schema from a working cluster in order to create a new empty cluster?
Thanks

Hi,
Since schematool has been removed from Cassandra is there a way to extract
the schema from a working cluster in order to create a new empty cluster?

This one is actively maintained, and (as far as I know) is being used
in production at Rackspace.
