At those rates, to avoid hot spots, and maintain rows in a manageable size
(~10MB or so), maybe you should partition every 5 or 10 minutes per app_id, so
your partition key looks like app_id + MMDDHHmm i.e 1234_201305081300,
1234_201305081305, 1234_201305081310, 1234_201305081315, etc.

Is there a way in Cassandra that we can know which node has the replica for the
data ? if we have 4 nodes and RF = 2, is there a way we can find which 2 nodes
have the same data ?
Thanks,

I have a 3-node cluster in production and a single-node development cluster. I
tested snapshotting a column family from the 3-node production cluster,
grouping the files together, and restoring onto my single node development
system. That worked fine. Can I go the other direction? It's not
You want to use sstableloader when the cluster sizes are different; it
will stream things to the right places in the new one.

Hello,
I have a cluster of 4 nodes and two of them are on different schema. I
tried to run the commands described in the FAQ section but no luck (
http://wiki.apache.org/cassandra/FAQ#schema_disagreement) .
After running the commands, I get back to the same issue. Cannot afford to
lose the data

This tells you where a key lives. (you need to hex encode the key)

Hi
I have a 3-node SSD-based cluster, with around 1 TB data, RF:3, C* v.1.2.0,

At the time of normal operation there was 800 gb free space on each node.
After the crash, C* started using a
