If I understand your correctly, you just want to add 8 nodes to a ring that
already has 2 ?
You could add the nodes and manually assign them tokens following the
guidelines here http://wiki.apache.org/cassandra/Operations
I'm not sure how to ensure the minimum amount of data transfer though.
Thanks for the anwser.
It was not exactly my point, I would like to know if in a 10 nodes rings if
it is possible to restrict replication of some data to only 2 nodes, and
other data to all nodes ?
Regards.

Yes, on a per-keyspace basis with NetworkTopologyStrategy (in 0.7).

Was the node that should have the other replica of this row down when

No, all nodes were up and running while the single key was inserted.
The insert however was with consistency One. I assume however that the replicas
are still written in this case.
It is btw also very reproducible.

Hi,
I am trying to iterate over the entire dataset to calculate some
information. Now the way I am trying to do this is by going directly to the
node that has a data range, so here is the route I am following
- get TokenRange using - describe_ring
- then for each tokenRange pick a node and

- Will all writes eventually reach all nodes (of the 3 nodes)?
I believe that if read repair is completely off, then for data that
was written that did *not* get saved by hinted hand-off, would not
propagate until anti-entropy as part of a 'nodetool repair' or perhaps
Also, your Mapper class needs to look like this:
MyMapper extends MapperByteBuffer, SortedMapByteBuffer,
IColumn,Text,SumWritable ... with all the necessary fixes to the map method.

Interesting. Does it simplify further to RF=1 and 2 nodes?

Aditya,
Can you reproduce the problem locally with pig -x local myscript.pig?
Also, moving this message back to the cassandra user list.

Cassandra keys and values are just bytes. My values range from simple doubles
to complex objects so I need to serialize them with something like avro, thrift
or protobuf.
Since I am working in a test environment and casssandra is moving to avro I
decided to use the avro protocol to

We are moving towards treating Thrift more as a driver than as a
format itself, and using libraries like Hector, pycassa, and phpcassa
from the client.

Hello,
We've had Cassandra running in a single production data center now for several
months and have started detailed plans to add data center fault tolerance.
Our requirements do not appear to be solved out-of-the-box with Cassandra. I'd
like to share a solution we're planning and find
It's been about a month since our last stable update and we've
accumulated a few changes[1] worth having, so I'm pleased to announce

If you're coming from a version older than 0.6.6 then please be sure to
read the release notes[2]; upgrades from 0.6.6. should be completely
Yeah, that's really microsecond latency. Note, though that this isn't
the full request timing, its just the storage proxy down, so it
doesn't account for any latency added by thrift or the network.
