Yes - that ticket was done by Nirmal Ranganathan for the intention of getting support in Cassandra. That's just for a java client though. In the future, I wonder if the CQL driver level is the right place for client encryption. On Aug 11, 2011, at 11:26 PM, Vijay wrote:

Installing Brisk on an existing Cassandra cluster?

Hi, Is it possible to add Brisk to an existing Cassandra cluster? The install packages all seem to bundle Cassandra(?) Basically I would like a tar.gz (as I'm on a Mac...) dist of Brisk which I can unpack and deploy on my already running Cassanda cluster. Or is there some tight integration (read

Vijay made a good point off list, thrift-106 is about Java support, but other languages have been implemented or at least have tickets to follow for them: Python support (thrift 0.7): https://issues.apache.org/jira/browse/THRIFT-1068 C++ support (thrift 0.7):

Restarting servers

2011-08-12 Thread Jason Baker
So restarting cassandra servers has a tendency to cause a lot of exceptions like MaximumRetryException: Retried 6 times. Last failure was UnavailableException() and TApplicationException: Internal error processing batch_mutate (using pycassa). If I restart the servers too quickly, I get all

You need to wait for the servers to be up again before restarting the next one. nodetool ring on one of the servers you aren't restarting will tell you when it is back up. You can also watch for Starting up server gossip in the log file to know when it is starting to join the cluster again.

It's pretty easy to fix. For background read this page on the wiki http://wiki.apache.org/cassandra/Operations also have a look at the help in the CLI, just type help; If you want to reduce your RF use an update keyspace statement and change the RF down to 1. You can increase the RF as well,

Turn the logging up to DEBUG, if you want to you can do it just for org.apache.cassandra.service.StorageProxy , and look for… * forwarding counter update of key… when the coordinator is forwarding the counter update * insert writing local replicate… when a counter mutation is applied locally
