Dear Community,
advice from you needed.
We have a cluster, 1/6 nodes of which died for various reasons(3 had OOM
message).
Nodes died in groups of 3, 1, 2. No adjacent died, though we use
SimpleSnitch.
Version: 1.1.6
Hardware: 12Gb RAM / 8 cores(virtual)
Data: 40Gb/node

how could I watch the heap usage then since jconsole is not able to connect
Cassandra at that time?
Trying delete the saved cache and restarting.
there is no problem for me to do so. But
hi Cassandra Developers,
I am experiencing huge commitlog size (200+G) after inserting huge
amount of data.
It is a 4-node cluster with RF= 3, and currently each has 200+G commit
log (so there are around 1T commit log in total)
The setting of commitlog_total_space_in_mb is default.
I am using 1.

No really, you can have a slice that starts i

What language ?
Check the Java http://code.google.com/a/apache-extras.org/p/cassandra-jdbc/ and
python http://code.google.com/a/apache-extras.org/p/cassandra-dbapi2/ drivers.

That's what I thought it said earlier in the email thread.

Yes, 8 bytes on disk.

The https://github.com/sebgiroux/Cassandra-Cluster-Admin app does some
of what you're asking. It allows basic browsing and some admin
functionality. If you want to run actual CQL queries though, you
currently need to use another app for that (like cqlsh).

I create 2 keyspaces in the start of application, using embedded cassandra

column families in this 2 keyspaces.
I put a "Thread.sleep(3000);" in the middle of the c

So that was it! :-)
