Hello,
While digging more for this I've found these :
Can we have a hope that counters will be replayed as safely as a classical

issues.apache.org/jira/browse/CASSANDRA-2495 ? I thought that replaying a
write from the client didn't lead to over-counts contrary to the internal

Hi Maxim,
Sorry for the late reply but I was away for a course. Lower the
memtable_flush_after_mins for your low traffic CFs. If in the meantime you
upgraded to 1.0 (which by the way 1.0.3 for me ended not working and me
converting a lot of data to it) I think there was a discussion you sent me

Hi Sasha,
Replying to the old thread just for reference. We've released a code
which we use to store emails in Cassandra as an open source project:

Hope you find it helpful.

Hi, all
I am confused by my stress testing result.
The test environment:
One Cassandra node, one client
The size of each row is 1MB, and the client write 10 rows continually.
Totally data size is 100GB.
First, my client connected to the server by 100Mbs Ethernet.
The result was 7.3MB/s.

Hi Rustam,
Thanks for posting that.
Interesting to see that you opted to use Super Column's:
https://github.com/elasticinbox/elasticinbox/wiki/Data-Model ..
wondering, for the sake of argument/discussion .. if anyone can come
up with an alternative data model that doesn't use SC's.

Hi Sasha,
There's been a lot of fud in regards to SuperColumns. But actually in
our case we found them quite useful.
The main argument for using SC in that case is that message metadata is
immutable and in most of the cases read and written alltogether (i.e.
you fetch all message headers
Works if you turn off mmap?
We run without mmap and see hardly any difference in performance, but with huge
benefits in the form of a memory consumption which can actually be monitored
easily and it just seem like things are more stable this way in general.
Just turn off and see how that
Hi,
I've also decided to give the C++ Thrift a try, but I can't seem to
compile the simple examples from
http://wiki.apache.org/cassandra/ThriftExamples .
I get lots of errors like :

You need to run repair on the node once it is back up (to get back the
data you just deleted). If this is happening on more than one node you
could have data loss...

Traditionally there are two places to go. Twitter's ruby client at
https://github.com/twitter/cassandra or the newer cql driver at
http://code.google.com/a/apache-extras.org/p/cassandra-ruby/. The latter might
be nice for green field applications but CQL is still gaining features. Some

Hi Ramesh,
Every time I have seen this in the last year it has been caused by bad
hardware or bad memory. Usually we find errors in the syslog.
Jeremiah is right about running repair when you get your nodes back up.
Fortunately with the addition of checksums in 1.0 I don't think that the
How can you possibly trace a read/write in cassandra's codebase when it
uses so many threadpools/executers?
I'm just getting into threads so I'm not to familiar with how one can trace
things while in debug mode in IntelliJ when various thread pools are
processing things etc.
normally I'd just fire up debug in eclipse, make a break point on the
Cassandra.server methods.

Thanks Ben and Jeremiah. We are actively working with our 3rd party
vendors to determine the root cause for this issue. Hopefully we will
figure something out. This repair procedure is more like a last resort
which i really don't want to use but something to keep in mind if such
necessity arises.
Hi,
From the source code I can see that for each key, the hash (token), the key
itself (ByteBuffer) and the position (long. offset in the sstable) are stored
into the key cache. The hash is an MD5 hash, so it is 16 bytes. So, the total
size required is at least 16+size-of(key)+4 which is 20
