Yes. That's the problem. Thanks Jonathan.
I'm actually using trunk against a 0.7. How can I generate the distro in
trunk?
Forgive my ignorance, I'm more used to maven.

Aaron, when using the RackInferringSnitch, is the octet correlated from the
rpc_address or listen_address?
I just noticed that when I tried to configure this locally on my laptop I
had to "0" (127.0.0.1) instead of "160" (192.160.202.235)

Great that makes perfect sense - I apologise for not getting this right it

Consistency is not performance, it's a whole new thing to tune in your
application. If you have performance issues deal with those as performance
issues, better code / data model / hard ware.

The strategy_options for NTS accept the data centre name and the rf,
[{ : }]
Where the DC name comes from the snitch, so…
SimpleSnitch (gotta love this guy, in there day in day out putting in the hard
yards) puts all the nodes in "datacenter1" which is why thats in the defaults.

Thanks Aaron, didn't seen your answer before mine.
I do agree for 2/ I might have read error. Good suggestion to use

Maybe using LOCAL_QUORUM might be a good answer and will avoid headache

I've not been able to find how endpoints are determined for the read
request, but I guess endpoints are just coming from the cu
Your current approach to Consistency opens the door to some inconsistent
behavior.

If you read from DC2 at CL ONE and the data is not replicated it will not be
returned.
> 2/ Will Cassandra try to get the data from DC
Okay, in a previous post, it was stated that I could use a
NetworkTopologyStrategy in a singel data centre by setting up my keyspace
with:
create keyspace KeyspaceDEV
with placement_strategy =
'org.apache.cassandra.locator.NetworkTopologyStrategy'
and strategy_options=[{datacenter1:3}];

The way specify more restrictions to the query is to specify them in the
index_clause. The index clause is applied to the set of all rows in the
database, not a sub set, applying them to a sub set is implicitly supporting a
sub query. Currently it's doing "select then project", this would be "s

This has been proposed a few times, there are some good use cases for
it, and there is no current mechanism for it, but it's been discussed
as a possible enhancement.

Has anyone done any work on what I'll call "selective replication" between DCs?
I want to use Cassandra to replicate data to another virtual DC (for
analytical purposes), but only "inserts", not "deletes".
Picture having two data centers, DC1 for OLTP of short lived data (say 90 day
window) an

Added to NEWS:
- After upgrading, run nodetool scrub against each node before running
repair, moving nodes, or adding new ones.

Hi,
So, here's the backstory:
We were running Cassandra 0.7.4 and at one point in time had a node in the ring
at 10.84.73.18. We removed this node from the ring successfully in 0.7.4. It
stopped showing in the nodetool ring command. But occasionally we'd still get
weird log entries about faili
Hello,
I have 2 datacenters. Cassandra is configured as follow:
- RackInferringSnitch
- NetworkTopologyStrategy for CF
- strategy_options: DC1:3 DC2:3
Data are written using CL LOCAL_QUORUM so data written from one datacenter will
eventually be replicated to the other datacenter. Data is always
Why it's radically?
It will be same get_indexes_slices search but in specified set of rows. So
mostly it will be one more Search Expression over rowIDs not only column
values. Usually the more restrictions you could specify in search query, the
faster search it can be (not slower at least).

When moving from 0.7.x to 0.8.5 do I need to scrub all sstables post
upgrade?
NEWS.txt doesn't mention anything about that but your comment here seems
to indicate so:

That's a pretty old JDK. You should upgrade.

thanks a lot for the help!
I have read the post and think 0.8 might be good enough for me, especially
0.8.5.
also change gc_grace_seconds is a acceptable solution.
