Compaction reads and writes are both sequential, and 0.8 allows
setting a MB/s to cap compacti
You must have given it a delete timestamp in the "future."

This really depends on your disks setup.
When you run iostat under high load, do you see a high number of r/s but the
rMB/s is not so great?
I usually use:
iostat -x -m sdb sdc 1 to monitor situation like this.
In my case my disk setup is the following:
OS --> /sda
Cassandra CommitLogs --> /
Sorry, Cassandra version is 0.7.4

I'm having a strange behavior on one of my cassandra boxes, after all
columns are removed from a row, insertion on that key stops working (from
API and from the cli)
[default@Agent] get Schedulers['atendimento'];
Returned 0 results.
[default@Agent] set Schedulers['atendimento']['test'] = 'dd';

I have three nodes and RF=3, every time it is do minor compaction, the
cpu load(8 core) get to >30, and iostat -x 2 shows utils is 100%, is
that means I need more nodes? the total data size is <60G
thanks!

How is it called in the "ps"?
Because I have a strong feeling that it tries to load... But for some
reason that is be on me it does not.
Is there a log file, or something?
Thanks again.

No, I did start it.
This is what I got when I started it:
INFO 16:00:38,053 Logging initialized
INFO 16:00:38,119 Sucessfully Hijacked FieldCacheImpl
INFO 16:00:38,151 Logging initialized

And then it stop... So I typed enter on the keyboard...
Sounds like you forgot to start solandra after you built it.
cd solandra-app; ./bin/solandra
You can verify it's running with jps look for SolandraServer.

Hi,
I have a server on RackSpace and it seems that when I use "ant" it
makes Apache2 crash. I don't if this is normal?
Maybe it's because I have 256MB for RAM. Could it be?
Should I get more RAM?
Also, when I use the command "ps -A" I don't seem to be able to
identify which is Solandra... How c
