Benedict I really don't want to turn this into a battle about who's opinion is
more valid and I really respect all the good work you've done for Apache
Cassandra.
I'll just reiterate that I'm comfortable saying 0.6 is a good starting point
and it is often not the ideal once you go through more t
Hi,
We recently started getting intermittent timeouts on primary key queries
(select * from table where key=)
The error is : com.datastax.driver.core.exceptions.ReadTimeoutException:

You aren't achieving quorum on your reads as the error is explains. That
means you either have some nodes down or your topology is not matching up.
The fact you are using LOCAL_QUORUM might point to a datacenter mis-match
on node count + RF.
What does your nodetool status look like?

Hi,
Could someone help me understand the output of the following command
select token from system.local where key = 'local';
I guess, it shows a set of tokens,
How to interpret the primary token range owned by that particular node.
Sample output
{'-1035756551821816651', '-108957861241888777', '-11
Siddharth,
This is the tokens assigned to your local node. It looks from this that
you have 256 vnodes set. The system.local only stored information on the
local node.
Thanks,

Hi Eric,
Thanks for your reply.
I know about V nodes, and token ownership.
If I want to find the token range, how do i do that from this data?
For eg, the 1st entry is -1035756551821816651. which range is it, i.e. is
this the start/end, and how to find the other extremity of this range.
Thanks,

Hi all
I am running C* 2.1.12 in AWS EC2 Classic with RF=3 and vnodes(256
tokens/node). My nodes are distributed in three different availability
zones. I want to scale up the cluster size, given the data size per node it
takes around 24 hours to add one node.
I wanted to know if its safe to add mu
Hi Aiman,
Best practice would be to map cassandra racks to AWS availability zones. If
you are following this then you would add one node per AZ to keep the
number of nodes in each rack balanced.
It is technically possible to add multiple nodes simultaneously (at least
joining simultaneously - you
