Hi,
What's the correct procedure to drop a keyspace? When I drop a keyspace, the
files of that keyspace don't get deleted. There is a JIRA on this:
https://issues.apache.org/jira/browse/CASSANDRA-4075
Is this a bug or I'm missing something?
I'm using Cassandra 1.1.2 on Ubuntu Linux with Sun
Isn't that obvious http://wiki.apache.org/cassandra/NodeTool check drain

There is one peculiar thing about this problem
When I copy the cluster to other 2 servers (much weaker servers in means of CPU
and RAM) and run cassandra there, I see no massive CPU load and no huge GC
times. Thus I suppose it has something to do with hardware or software

Hi!
To clarify it a bit more,
Let's assume the setup is changed to
RF=3
W_CL=QUORUM (or two for that matter)
R_CL=ONE
The setup will now work for both read and write in case of one node failure.
What are the disadvantages, other than the disk space needed to replicate

So your GC times may be strongly [1] affected by swapping.
IIRC, also snapshotting is more expensive and may trigger more swapping.
I would start with turning JNA mlockall on [2].

It seems I did make a mistake somewhere before (or I mistyped it) - it

I wonder if it's possible to have access to metadata regarding a

Thanks very much for your help!

Hi guys,
Can anyone explain what all time blocked and blocked columns mean in
tpstats? I have a 2 node 1.1.2 cluster, on which one of the nodes has the
following output for FlushWriter. The other node is on 15 'All time
blocked'. Do i need to 'unblock' this?

Thanks for the pointer! It sounds likely that's what I'm seeing. CFStats
reports that the bloom filter size is currently several gigabytes. Is there any
way to estimate how much heap space a repair would require? Is it a function of
simply adding up the filter file sizes, plus some fraction of

Just so you know, you can control bloom filter sizes now with the per-cf
bloom_filter_fp_chance attribute.
