Ack, I agreed to speak at http://nosqleu.com/, I never did hear a
final date but they put up a schedule online (april 20-22).
But, 22 probably is a better date, and Eric and Stu are fully capable
of representing rackspace without me. :)

Yes, I was expecting the column names to come back as strings like the way
it does with 0.5.1.

Except that for a major compaction the whole thing gets put in one

it's ordered by the column name as determined by the subcolumn

Hi.
If I iterate over SuperColumn.getSubColumn(), do I get
columns sorted by the column name?
What does this query return?
Is there a way to do a range query and get the row count? (e.g. row
start = TOW' row end = 'TOWZ')
Thanks

It counts the number of columns in a row or super column.
Try: http://wiki.apache.org/cassandra/API#get_count

Not that I'm aware of.
I have a model which doesn't store any columns since I could

I'm still wondering what happens when you have something like 2 500GB disks,
with 2 sstables which use up 25OGB, one on each disk, then a major compaction
occurs. Will it still compact and probably fill up a disk (especially with
the 2x overhead of compaction mentioned either here or on the

Can you provide more information (an example would be very nice) on
using batch_mutate deletes to build a time-series store in Cassandra? I
have been reading up on batch_mutate from the Wiki:

It seems to me that since the outer map of
a lot. In the trillions (where each column name stores the valuable
information and column values are empty). I read somewhere that
column size should be in the single MB digits. Storing it in the key
allows true horizontal scalability. Is this true?
