Hi,
I have a question about cassandra 1.1
Just wanted to confirm if key_cache_size_in_mb is the maximum amount of
memory that key cache will use in memory? If not, what is it?
My observations:
With key cache disabled, I started cassandra. I invoked Full GC through
jconsole a couple of times just
I found a fix for this one, rather a workaround.
I changed the rpc_server_type in cassandra.yaml, from hsha to sync, and the
error went away. I guess, there is some issue with the thrift nonblocking
server.
Thanks

Thanks Radim.
Radim, actually 100 reads per second is achievable even with 2 disks.
But achieving them with a really low avg latency per key is the issue.
I am wondering if anyone has played with index_interval, and how much of a
difference would it make to reads on reducing the index_interval. I

This is hampering our testing of cassandra a lot, and our move to cassandra
1.0.9.
Has anyone seen this before? Should I be trying a different version of
cassandra?

Hi,
i have created 1 node cluster of cassandra 1.0.9. I am setting this up for
testing reads/writes.
I am seeing the following error in the server system.log

Thanks Benjamin. I realised that, i have reverted using cleanup, got it back

Hi,
I have a few questions and was looking for an answer.
I have a cluster of 7 Cassandra 0.6.5 nodes in my test setup. RF=2. Original
data size is about 100 gigs, with RF=2, i see the total load on the cluster
is about 200 gigs, all good.
1. I was looking to increase the RF to 3. This process e
Thanks to driftx from cassandra IRC channel for helping out.
This was resolved by increasing the rpc timeout for the bootstrap process.

Hi,
I have a cassandra cluster of 4 machines, and I am trying to bootstrap 2
more machines, one at a time.
For both these machines, the bootstrapping stays stuck after the streaming
is done.
When the nodes come up for bootstrapping, I see all the relevant messages

I am using Cassandra 0.6.5, and playing with bootstrapping, decommissioning
nodes.
The latest one i hit is the exception down below. I got this exception twice
on the source machine while streaming, in 2 different scenarios (both
involved streaming though)

Hi,
version: cassandra 0.6.5
I am trying to bootstrap a new node from an existing seed node.
The new node seems to be stuck with the bootstrapping message, and did not
show any activity.
Only after i checked the logs of the seed node, i realise there has been an
error:
