Hi all,
I'm trying to create a keyspace through the CQL Binary Protocol but lamely
failed at doing this simple task with 1.2b2/cql3.
Various command tried:
DEBUG 18:08:23,240 Received: OPTIONS
DEBUG 18:08:23,240 Responding: SUPPORTED {CQL_VERSION=[3.0.0],
COMPRESSION=[snappy]}
DEBUG
Forget about it, should have read
https://github.com/apache/cassandra/blob/trunk/doc/cql3/CQL.textile instead
of source snapshot (not merged in 1.2-b2 snapshot ?)

Hello,
Using a 2 nodes fresh cluster (127.0.0.1 127.0.0.2) running latest 1.2,
I'm querying system.peers to get the nodes of the cluster and their
respective token. But it seems there is a problem after either node restart.
When both node starts up, querying system.peers seems ok:

Executing a query using an invalid CL with binary protocol leads to an

Hi,
That's not a good reason imho. This would have been better to have chunks of
data (like in the good old IFF file format).
If the client is not able to read the chunk, just skip it. And frankly,
that's not a few more bytes that would have killed us.
As an example, request tracing was added
You can quickly create a query using dapper and then transfer all your rows
using cassandra-sharp actually. The only thing you have to do is to create a
class to materialize a row and obviously the SQL and CQL statements.

Dear Santa, here is my wish list :)
- support for atomic operations or batches (if QUORUM fails, data should not
be visible with ONE)
- TTL on CF, rows and counters
- restart the TTL when a row, column or CF is touched
- streamed data transfer (both send receive). At least for receive
- support for atomic operations or batches (if QUORUM fails, data should
not be visible with ONE)
zookeeper is solving that.
Yeah, I can use HBase too.
I might have screwed up a little bit since I didn't talk about isolation;
let's reformulate: support for read committed (using DB
I do not want to use HBase because Cassandra is way far easier to deploy and
it is working pretty well - and for the 99% of our apps the model fits
perfectly. The other 1% has a workaround by ordering writes. I assume the
trade off anyway :)
Don't miss the point: I love Cassandra and the way it

I bet you are using cql commands in cassandra-cli.
If you are using cli, use instead:

Jonathan provided a patch for that. You can apply it on top of 1.1.

Hi,
It's normal.
Keys to replicas are determined with a hash (md5) when using the random
partitionner (which you are using I guess).
You probably want to switch to the order preserving partionner or tweak your
data model in order to rely on 2nd index for such filtering.

Hi,
Using nodetool for each node one by one:
1. disablethrift
2. drain
3. Shutdown your daemon
4. Modify the config
5. Restart the node
You won't lose the data on your nodes - clients might see a node down, it is
usually not a problem if your c* client is smart enough. You also won't lose
You'd better use version 1.0.9 (using this one in production) or 1.0.10.
1.1 is still a bit young to be ready for prod unfortunately.

You do not need to have 700 Go of data in RAM. Cassandra is able to store on
disks and query from there if data is not cached in memory. Caches are
maintained by C* by itself but you still have to some configuration.
Supposing you want to store around 800 Go and with a RF=3, you will need
