Hi all.
I have very SLOW READ here. :-(
I made a cluster with three node (aws xlarge, replication = 3)
Cassandra version is 1.0.6
I have inserted 1,000,000 rows. (standard column)
Each row has 200 columns.
Each column has 16 byte key, 512 byte value.
I used Hector createSliceQuery to get one col
hmmm.. just an update.
sorry, it doesn't work.
I did get multiple web port listen,
but opscenter seem to be using same resource or what and it can not
have multiple running.

never mind.
it works.
my second cluster didn't have any keyspace, that why.

Hi,
I know OpsCenter doesn't support multiple cluster yet.
I tried to install & run multiple OpsCenter in a server with different port.
different port for web and agent. same cassandra jmx, thrift port.
But second OpsCenter doesn't show any cluster node number. (web is working)
Am I missing a conf
Hi, I'm doing stress test with tools/stress (java version)
I used 3 EC2 Xlarge with 4 raid instance storage for cluster.
I get write TPS min 4000 & up to 1
but I only get 50 for read TPS.
is this right? what am I doing wrong?
these are option.
java -jar stress.jar --nodes=ip1,ip2,ip3 --consist
; So, I recommend checking the data on a distribution node.

Hello.
I'm using cassandra 0.8.6
with nodetool tpstats, dropped statistics are shown.
when drop happens... what can I do?
are there ways to turn on debug messages or to look into?
thanks.
Hi,
I'm using Hector 0.8.0-2 & Cassandra 0.8.6 on EC2 XLarge systems.
I have a Supercolumn with 10 sub columns.
Most of times it works, but occasionally I find last sub column is
missing completely.
I checked our program that it's successfully inserting all 10 sub
columns into HColumn
just before
Thank you!!
This helped me a lot!

BytesType vs. UTF8Type. which is better in performance?
I assume Bytes be faster in compare.. but how much faster is it?
For large large large data set, will it have significant different?
I love to use UTF8 and be able to read value from cli. :-)
*IF* it doesn't degrade performance too much.
