Hi Alain,
have you had a look at the following tickets?
CASSANDRA-4905 - Repair should exclude gcable tombstones from merkle-tree
computation
CASSANDRA-4932 - Agree on a gcbefore/expirebefore value for all replica
during validation compaction
CASSANDRA-4917 - Optimize tombstone creation for Expir

QUORUM. Yes,
I have actually tested repair in many interesting scenarios:
Once I joined a node and forgot autobootstrap=true
So the data looked like this in the ring

8GB
new node
0GB
right node
8GB
After repair

10 GB

right node
12 gb
We do not run repair at all. It is better
Hello, someone can help me to use the Object CassandraServer() in version
1.2.4??
I was using this in version 1.1.10, and thats work, but was happening
something that I can not solve (sometimes my cpu up to 100% and stay
forever) so I decide to do the upgrade.
I start the cassandra with EmbeededCa
If you are using hector it can setup the embedded server properly.
When using the server directly inside cassandra I have run into a similar
problem..

Hello All,
Is using multiple cursors simultaneously on the same C* connection a good
practice?
I've an internal api for a project running thrift, I then need to query
something from C*. I do not like to create a new connection for every api
request. Thus, when my service initially starts I open a

ThriftSessionManager.instance.setCurrentSocket(new

I will need to execute this line every time that I need to do somiething in
Cassandra? Like update a collunm family.
Thanks for reply.

distributed systems, inconsistencies can arise between replicas due to

You are doing something wrong. What I was suggesting is only a hack for
unit tests. Your not supposed to interact with CassandraServer directly
like that as a client. Download hector and use the correct client libraries.

Hi All
I am doing very small inserts into Cassandra in the range of say 64
bytes. I use a C++ Thrift client and seem consistently get latencies
anywhere between 35-45 ms. Could some one please advise as to what
might be happening?
thanks
