I'm having a strange problem when some of get_column and get_slice calls
fails to TSocket: Could not write 85 bytes paja.dev.pri:9160 exception.
The problem appears on some but not all calls to get_column and also
some times to other calls.
I'm using 0.6.3 on a single host (it's a development
I'm having a simmular problem, but i get verry random read problems 4
bytes timouts. (mailed before about this)
The only fix i got/found was, switch to framed transport instead of
buffered transport,
but i still have the same problem (less frequent)
running debian packaged cassandra (0.6.1)
Hi all,
I'm newbie in Cassandra, I have a question about which node is coordinator
node in my cluster.
I have A, B, C, D, E, F and G nodes. if I run a write operation on A node,
and key range between A and B, so the A node is responsible to write the key
to B, C and D nodes(RF=3) ? and does it
Hi Pieter,
I switched to framed transport but it didn't completely fix the problem.
PS. i see there is 0.6.3 now available for debian, I'll test that version..
like you said you don't have the issue on 0.6.3 it might be fixed there..
I'm sorry if I didn't tell clearly enough: the problem
What were the right questions? I view Facebook's move away from
Cassandra as somewhat significant.
And are they indeed using HBase then, and if so, what were the right
answers?

Which ever node the client connects to is the coordinator node. It will take
care of sending the messages to the nodes who will do the actual work.
If you have multiple nodes try a DNS round robin to distribute client
connections around.

For here, I guess it's only significant if there are interesting
technical reasons. I find Cassandra's design tradeoffs close to optimal,
so
Hi All,
I have a query related to deleting a column inside a super column
The following is my cassandra schema
[cache_pages_key_hash] = Array

[2] = 4c330e951f18b
FB Inbox Search still runs on Cassandra and will continue to do so. I should
know since I maintain it :).

Is there a document anywhere with estimated release dates for the 0.7
and 0.8 versions of cassandra? I've seen

which indicates progress towards 0.7, but I haven't had much luck with
finding date estimates. I'm especially
Along this line, is it known if upgrading from 0.6 to 0.7 will require cluster

This is a ridiculous statement by some newbie I guess , We today have a 150

simply because they hear rumors about Facebook or some other large website

Rather than creating a new keyspace consider using the domain as part of a key.
Generally an application has a single keyspace and a few column families
(enough to response to the queries you expect).
Think about using the domain as the full or partial key, and then creating
column families

You might want to clarify that this advice applies to all topics of discussion

Hi all,
I have A, B, C, D, E, F and G nodes(RF=3), if I run a write
operation(CL=ALL) on A node(coordinator), and the key range between A and

B node is down during the write operation, does it return failure(CL=ALL) to
