Upgrading from 0.6.5 to 0.6.6 is just a simple rolling restart on all
your nodes. Upgrading from 0.6 to 0.7 is a lot more work: you need to
change your code as the api changes and you need to shutdown the
entire cluster for upgrade.
I'm just about to upgrade my five node cluster to 0.6.6 and I'm

Thanks for the advice. Follow up questions:
a) is 0.6.6 compactable with 0.6.1?
Yes, you can upgrade one node at a time and it will particpate w/ the
0.6.1 nodes until they are done too. Just restart w/ 0.6.6, no data

Aaron,
I updated the cassandra files and but still receive the same error (on
client side) with a different line number 551:

Hi,
If I do a secondary index look up with multiple index expressions (1) that
do not result in a match then I get a looping entry in the log until I
terminate the cassandra server.
e.g. (I'll use a pseudo notation to indicate the examples)
lookup( [ { SecondaryIndexedColumnName, ColumnValue
can you create a ticket with a test case?

Hi,
I'm using TimeUUID/Sort by column name mechanism. The column value can
contain text data (in future they may contain image data as well) leading to
the possibility of a row out-growing the RAM capacity. Given this background
my questions are:
a] How many columns are recommended against one
I wrote some thoughts about this on my blog. I think it's still mostly correct:

a) 10 mil sounds fine. Just watch out for compaction. Huge rows can kill
you there,
from my understanding.
b) Use RandomPartitioner unless you absolutely have to use something else.
c) If you're inserting all along one row and only moving to another row when

The optimization definitely shaved off some time. Now it is running about 3x
CFSTATS reported time. Below are the logs.
There is a ~300ms time frame after the last ResponseVerbHandler prior to the

Hmm, I don't have a java client that does all this. All of my stuff is in
erlang using the thrift client.
I can certainly raise a ticket and describe the problem though.
If the CLI supported querying by index I'd see if I could knock up an script
that did it but I don't think it does.

I'm operating a several two-node clusters (version 0.6.5) on VMs in our
development and test environments.
After about a week of operation under similar conditions, one of them
started throwing this:
WARN [main] 2010-10-12 08:08:31,245 CustomTThreadPoolServer.java (line 104)
Sounds good. You're right, CLI doesn't support this yet (but will shortly!)

I have a query regarding the insert operation. The insert operation by default
inserts an new row or updates an existing row. Is it possible to prevent an
update but allow only inserts automatically ( especially when multiple clients
are writing to cassandra)? I was wondering if
Hey guys,
I'm having a problem with pig and cassandra and was hoping someone could
point me in the right direction. I've setup Pig and Cassandra and I'm able
to run through the example shown in the README.txt - I can view a list of
top column names. That's all good stuff.
