I don't think thats solves my problem. The question really is why can't we
use ranges for both time columns when they are part of the primary key.
They are on 1 row after all. Is this just a CQL limitation?

What's the latest on the maximum number of keyspaces and/or tables that one
can have in Cassandra 2.1.x?

We are planning to upgrade soon. But in the meantime, I wanted to see if we

Thanks Eric for the information. It looks like it will be supported in
future versions.

Eligibility_state being a collection. The above query would be used
frequently.
Would you recommend collections for modeling from a performance perspective?

One of our nodes keeps crashing continuously with out of memory errors. I
see the following error in the logs -
INFO 21:03:54,007 Creating new commitlog segment

Hi,
I have a 2 DC setup(DC1:3, DC2:3). All reads and writes are at
LOCAL_QUORUM. The question is if I do reads at LOCAL_QUORUM in DC1, will
read repair happen on the replicas in DC2?
Thanks

Hi experts,
I am planning to upgrade from 0.8.4 to 1.+. Whats the latest stable
version?
Thanks

How did you solve your problem eventually? I am experiencing something
similar. Did you run cleanup on the node that has 80GB data?

Nick, do you think I should still run cleanup on the first node.

I did run nodetool move. But that was when I was setting up the cluster
which means I didn't have any data at that time.

Actually I am not worried about the percentage. Its the data I am concerned
about. Look at the first node. It has 102.07GB data. And the other nodes
have around 60 GB(one has 69, but lets ignore that one). I am not
understanding why the first node has almost double the data.

ranges its responsible for(which is everything). So unless I upgrade to
1.0.+, where I can use the -pr option is it advisable to just run repair on
the first node.

Can I infer from this that if I have 3 replicas, then running repair
without -pr won 1 node will repair the other 2 replicas as well.

But that says it was fixed in 0.8 beta. Is this still broken in 0.8.4?
I also don't understand why the data was inconsistent in the first place. I
read and write at LOCAL_QUORUM.

nable to reduce heap usage since there are no dirty column families
nodetool ring shows 48GB of data on the node.
My Xmx is 2G. I rely on OS caching more than Row caching or key caching.
Hence the column families are created with default settings.
Any help would be appreciated.

How do I ensure it is indeed using the SerializingCacheProvider.

Do we need to do anything special to turn off-heap cache on?

I know it doesn't. But is this a valid enhancement request?

decide which nodes can run repair concurrently. For example, if RF =3, and I
have 6 nodes, then 2 replicas which are responsible for different ranges in
the ring can run repair concurrently.

Do you guys see any flaws with this approach?
What happens when DC1 comes back up and we start reading/writing at QUORUM
again? Will we read stale data in this case?
Thanks

Hi all -
We're new to Cassandra and have read plenty on the data model, but we wanted
to poll for thoughts on how to best handle this structure.
We have simple objects that have and ID and we want to maintain a history of
all the revisions.

MyObject:
ID (long)
name
other fields

Guys,
Correct me if I am wrong. The whole problem is because a node missed an
update when it was down. Shouldn’t HintedHandoff take care of this case?
