Hi
I am using Cassandra 1.0.6 version in our production system and noticed that
Cassandra flushing the data to SSTable and the file size is < 10MB. With
under moderate write load, the Cassandra flushing lots of memtables with
small sizes. With this compaction doing lots of compactions.
O/S - Cent
We run some fairly large and busy Cassandra setups.
All of them without mmap.
I have yet to see a benchmark which conclusively can say mmap is better (or
worse for that matter) than standard ways of doing I/O and we have done many of
them last 2 years by different people, with different tools an
I know we had this conversation over on the dev list a while back:
http://www.mail-archive.com/dev@cassandra.apache.org/msg03914.html
I just wanted to let people know that we added the capability to our
cassandra-indexing extension.

Ah yes that's it exactly, including the time outs/errors. I wonder why
this didn't come up when I googled the error from my system logs.
Thanks!

Hi Sylvain,
Thanks for the quick response.
Yes. I don't know the difference from bind variable to "query
substitution". I'm a little confused, I just try to use your language.
:) In Oracle world, we called Binding Variable.
Can you give me a concise example for bound variables supported by BA
Just to close this item: with CASSANDRA-4314 applied I see no memory errors
(either Java heap or native heap). Cassandra appears to be a hog with its
memory mapped files. This caused us to wrongly think it was the culprit in a
severe native memory leak. However, our leaky process was a differ

Yes.
I guess it could be an artefact of the bulk load. It's not been reported
previously though. Try the cleanup and see how it goes.

Check the logs for GC problems.

Hi
I'm using version 1.1.1. I'm sorry about the lack of information, i don't
have stacktraces, nothig crash, just return empty, i explain, i do login as
usual, find in db if there is a user named X and who belongs to client Y,
if that is true i return the hash of password from db and do my checks.
What do you mean when you say you can't display the related documentations
using the help command? What does cqlsh do instead? I don't know about
any bugs in that area.

The option must actually include also the name of the yaml file:
Dcassandra.config=file:///Users/walmart/Downloads/Cassandra/Node2-Cassandra1.1.0/conf/cassandra.yaml

Hi Folks,
We wanted to have a single cassandra installation, and use it to start
cassandra in other nodes by passing it the cassandra configuration directories
as a parameter. Idea is to avoid having the copies of cassandra code in each
node, and starting each node by getting into bin/cassand
Hi,
I have a Cassandra installation where we plan to store 1Tb of data, split
between two 1Tb disks.
Tiered compation should be better suited for our workload (append-only,
deletion of old data, few reads).
I know that tiered compaction needs 50% free disk space for worst case situation. How do
Thanks very much, Jeff. It's exactly what I looked for...

You should be able to get most of this information from the datastax
documentation, e.g.
http://www.datastax.com/docs/1.0/references/cql/index for version 1.0.
