Subject: Re: Booting Cassandra v0.7.0 on Windows: rename
Jim, Jonathan thanks for the feedback.
I was trying something different and rattled through the whole deck in about
35-40 minutes.
I'll be doing the talk again at the Wellington Python Users Group this Thursday

I'm chunking up a larger blob. Basically the size of each row can vary
(averages around 500K - 1MB), with some outliers in the 50 MB range. However,
when I do an update, I can usually just read/update a portion of that blob. A
lot of my read operations can also work on a smaller chunk. The
Hi Tyler,
Thanks for the response. I decided to give up on it, and start my own Scala
based api modeled on Cascal since it's no longer supported.

I have a lot of No's for you. :)
As an example, I have 2 rows (1,2) with 2 columns (a,b). If I modify both
rows,

Did you look at Scromium?

Your referring to this: https://github.com/cliffmoon/scromium right? Thanks
for the tip, I'll give it a try.

I'd highly recommend looking at Hector (v2) as well. It's very nice.
I'm using it from Scala without any issues.
Rather than duplicating the effort of scromium, cascal, scalandra, and
not to mention Hector itself, perhaps it'd worthwhile taking a stab at
a Scala interface wrapping Hector?
It's hard to tell without knowing the the nature of the data you're writing,
but you might want to think about whether you can embed any sort of version
number and/or checksum into the column names of the chunk columns. That
way, you could very easily determine that the data you wanted to

What error are you getting?
Remember, get_count() is still just about as much work for cassandra as
getting the whole row; the only advantage is it doesn't have to send the
whole row back to the client.
If you're counting
Hello again.
We have 3 nodes and were testing what happens when a node goes down.
There is roughly 10gb of data on each node. The node we simulated dieing was
working just fine under the load. Then we killed it. The ring performed
admirably, But upon restarting the node it dies every
Looks like it's trying to load your row cache and running out of memory, probably because you reduced the memory. The cassandra-env.sh script would have been giving it 2GB.1Gb heap is probably going to be to small.Was this the same error you were getting before you reduced the memory ?Try deleting
If you're getting OOM with adaptive heap size of 1GB, reducing it to
1GB is not going to make things better. :)

I'm a little confused about #3. Hopefully this clarifying question won't turn
the one maybe into a no :).
I'm fine not reading the latest data, as long as on each individual read I see
all or none of the operations that occurred for a single one row batch_mutate.
My concern is do I have to
Hi,
Can you Please help me, why the pid file is not created in windows environment
when I try with C:\apache-cassandra-0.6.6\bincassandra.bat -p c.pid ?
Is there a better way to shutdown the cassandra server instead of kill pid?
Thanks,

Are there any C++ clients out there similar to Hector (in terms of features)
for Cassandra? I am looking for C++ Client for Cassandra 0.7.
Thanks,
Naren
Thrift is there..

Every time cassandra creates a new sstable , it will call the
CompactionManager.submitMinorIfNeeded ? And if the number of memtables is
beyond MinimumCompactionThreshold , the minor compaction will be called.
And there is also a method named CompactionManager.submitMajor , and the
call
