I'm down--we had a good mini-meetup last year at lunch. How about trying
to get something together on Wed or Thurs night?

Not that familiar with CQL in particular, but what timeout is set in
pycassa? It could be too low for your batch size. If your request is timing
out, it will do exponential back off between retries.

I'll be at Surge on Thursday, would love to meet up. Anyone else planning
to be there?

I think I've dropped all the indexes on a CF, but I see traces of them in
the CLI output of show keyspaces. I see a few validators left behind, and
one "built index". (output below)
1. Is there a better way to check schema for indexes?
2. I can't drop the "built" one so I assume they're all gone
le2json with expiring columns.

Perhaps I misunderstand your proposal, but it seems that even with your
manual key placement schemes, the row would still be huge, no matter what
node it gets placed on. A better solution might be figuring out how to make
each row into a few smaller ones to get better balancing of load and also

0.8.1 should be up--I've already installed it. Here's directions:

Not sure what the intended purpose is, but we've mostly used it as an
emergency disk-capacity-increase option. It's not as good as raid because
each disk size is counted individually (a compacted sstable can only be on
one disk) so compaction size limits aren't expanded as one might expect.

Are you using the order preserving partitioner or the random partitioner for
this CF? In order to get the results you expect, you'll need to use the
OPP.

There might not be a built-in way to do this, but if you make two rows for
each author, eg:
nabokov_fulltext [ 'lolita' : 'Lolita, light of my life ...' , ...]
nabokov_bookindex [ 'lolita' : None , ... ]
you could query the bookindex for each author without cassandra having to
load the full texts
Null response may mean an error on the server side. Have you checked your
cassandra server's logs?

It sounds like the problem is that the row is getting filled up with
tombstones and becoming enormous? Another idea then, which might not be
worth the added complexity, is to progressively use new rows. Depending on
volume, this could mean having 5-minute-window rows, or 1 minute, or

I should mention that it took me a while to figure this out too. Might be a
candidate for an improvement in the cli?

When I've gotten "null" as a result in cassandra-cli, it turned out to mean
that there were exceptions being thrown on the server side. Have you checked
your Cassandra logs?

Hi all,
It often takes more than two seconds to load:
- one row of ~450 events comprising ~600k
- cluster size of 1
- client is pycassa 1.04
- timeout on recv
- cold read (I believe)
- load generally < 0.5 on a 4-core machine, 2 EC2 instance store drives for
cassandra
- cpu wait generally < 1%

I don't know all the details of your case, but with serving static files I
suspect you could do ok with something that has a much smaller memory/cpu
footprint as you won't have as great of write throughput / read latency
concerns.
We've done hundreds of gigs in and out of cassandra 0.6.8 with pycassa 0.3.
Working on upgrading to 0.7 and pycassa 1.03.
I don't know if we're using it wrong, but the "connection object is tied to
a particular keyspace" constraint isn't that awesome--we have a number of
keyspaces used simultaneo
