I disable the disk cache of RAID controller, unfortunately it still lost
some data.
Disabling caching shouldn't be necessary so much as ensuring that all
layers honor write barriers properly. A battery backed cache that
survives a power outtage need not be disabled (and usually if you have

Thank you very much Peter !
After I disable the disk cache and change the cache write mode from
write-back to write-through, I saw the result I'd like to see.
It seems fsync() only synced the data to the disk cache but not the storage
devices while disk cache sync mode in write-back.
But I have
Hi guys,
I upgrade the 4-nodes cassandra 0.7.4 cluster to 0.8.0. Then, I do the
bin/nodetool decommission on one node, the decommission hangs there and I got
the following exceptions on others nodes.
ERROR [Thread-55] 2011-06-03 18:02:03,500 AbstractCassandraDaemon.java (line
113) Fatal
Could you please create a bug report for this in Jira
https://issues.apache.org/jira/browse/CASSANDRA
Please check the data directory on the node that encountered the error and
include any files names that have tmp in them.
Can you also check for log messages on the node you decommissioned at
Hi Aaron,
Thank you for your reply, I've reported a bug on the jira
https://issues.apache.org/jira/browse/CASSANDRA-2739 .
Since I'm not in the office now, so I will come up with more information and
try your methods when I'm in the office again, maybe next Monday.
Thanks.

Does reading quorum mean only waiting for quorum respones or does it mean
quorum respones with same latest timestamp?

Only waiting for quorum responses and then resolving the one with the latest
timestamp to return to the client.

We embed cassandra in our app. When we first load a cluster, we specify one
node in the cluster as the seed node. This node installs the schema using
StorageService.instance.loadKeyspacesFromYAML(). This call has disappeared
in 0.8.
How can we do the same thing in Cassandra 0.8?
Thanks,

Well it depends on how your CL is for writes. If you write with QUORUM and
then read with QUORUM then yes you will get at least

It means waiting for at least Quorum responses including the one data request
sent to the closest replica. The other replicas are asked to return a digest
of the data.
The responses are then reconciled and if a difference is detected columns with
the highest timestamps will be returned.

Hello,
I have read a lot about CQL and I looked into source and it seems that
just string, long and uuid can be used as column name/value in CQL
commands. Is there any way how to works with pure bytes? I.e.
SELECT BYTES(3412) FROM MyColumnFamily.
Actually, I wouldn't use CQL without this feature
You can use any AbstractType, including custom ones. The format
depends on AT.fromString; in the case of bytestype (CQL bytea) this
is hex:
SELECT 'd54' FROM MyColumnFamily
