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,
Are there any benchmarks that quantify how long nodetool repair takes?
Something which says on this kind of hardware, with this much of data,
nodetool repair takes this long. The other question that I have is since
Cassandra recommends running nodetool repair within
I know it doesn't. But is this a valid enhancement request?

I had 3 nodes with strategy_options (DC1=3) in 1 DC. I added 1 more DC and 3
more nodes. I didnt set the initial token. But I ran nodetool move on the
new nodes(adding 1 to the tokens of the nodes in DC1) . I updated the
keyspace to strategy_options (DC1=3, DC2=3). Then I started running nodetool
I have a 6 node cassandra cluster DC1=3, DC2=3 with 60 GB data on each

the weekly nodetool repair job. As a result, repair was interfering when we
were bulk loading data. I canceled repair by restarting the nodes. But

You should run repair. If the disk space is the problem, try to cleanup

You can limit the streaming data by running repair for each column family
separately.

Try running 'nodetool cleanup' on all of your nodes.

DataStax recommends not to run major compactions. Edward Capriolo's
Cassandra High Performance book suggests that major compaction is a good
thing. And should be run on a regular basis. Are there any ground rules
about running major compactions? For example, if you have write-once kind
of data
compactions, but some use cases could see some benefits

Hi experts,
We are planning to deploy Cassandra in 2 datacenters. Let assume there
are 3 nodes, RF=3, 2 nodes in 1 DC and 1 node in 2nd DC. Under normal
operations, we would read and write at QUORUM. What we want to do though is
if we lose a datacenter which has 2 nodes, DC1 in this case, we
Is there a good formula to calculate heap utilization in Cassandra pre-1.1,
specifically 1.0.10. We are seeing gc pressure on our nodes. And I am
trying to estimate what could be causing this? Using node tool info my
steady state heap is at about 10GB. XMX is 12G.
I have 4.5 GB of bloom filters
We are planning to upgrade soon. But in the meantime, I wanted to see if we
can tweak certain things.

They are on 1 row after all. Is this just a CQL limitation?
