ruuning for a while, you should set the -Xss to more than 160k when you
using jdk1.7.

hi list,
I am using Cassandra with 3 data centers, each DC has more than 10 nodes.
the schema for a keyspace:
{DC1:3, DC2:3, DC3:3}
now, I put some rows using hector with CL Local_Quorum in DC1 ，and then I
get a row with the same CL Local_Quorum in DC1，some exceptions were occured:

sliceRangeQuery.setRowCount(1);
current family has only abort 1 rows, each row has ~10columns, the data
abort 25k.

hey List,
I consider a way that can read all data from a column family, the following
is my thoughts:
1. make a snapshot for all nodes at the same time with a special column
family in a cluster,
2. copy these sstables to local disk from cassandra nodes.
3. compact these sstables to a single one
1 sstable you can do major compactions but that's not

Hi list
I'd like to connect to remote Cassandra using Java client, the following
code I use, but ImcompatibleClassChangeError was occured, the source that
was just dependent on the following jars:
apache-cassandra-1.0.9.jar, apache-cassandra-clientutil-1.0.9.jar,
apache-cassandra-thrift-1.0.9.jar
Thanks.
I just fix my problem, I missing a jar named libthrift-0.6.jar.

Hi
I think you can use an ordered partitioner to store the rows in order,
then, you can refer to the implementation of openTSDB which solves the
timeseries data using composite key in Hbase.

Hello,
Any suggestion abort it?
whether you use which one, they both contact Cassandra via thrift. I'd
suggest you to take look at RingCache, it can help you to compute the
endpoint of data on Client side since Cassandra will forward your request
on coordinator node.
and another solution is tha
Hello,
I would like to know which write wins in case of two updates with the
same client timestamp in Cassandra.
Initial data: KeyA: { col1:"val AA", col2:"val BB", col3:"val CC"}
Client 1 sends update: KeyA: { col1:"val C1", col2:"val B1"} on Sx
Client 2 sends update: KeyA: { col1:"val C2", co
Thanks Capriolo,
Umm.. so is there any background or history abort this issue?

Hello,
I'd suggest you to take look at the difference between Nosql and RDMS.

Hello,
I read the source code of SSTableIdentityIterator with v-1.0.9, and I
thought the following code is not necessary, did I miss anything?
RandomAccessReader file = (RandomAccessReader) input;
file.seek(this.dataStart);
here, the value of dataStart is assigned
