Hi all,
I'm working on transferring our thrift DAOs over to CQL. It's going
well, except for 2 cases that both use multi get. The use case is very
simple. It is a narrow row, by design, with only a few columns. When I
perform a multiget, I need to get up to 1k rows at a time. I do not want

the old naming
convention.
Thoughts?

Hey guys,
I'm working on migrating some data from 1.0.x clusters to a 1.2.16
cluster. Part of my testing is (locally) loading the old 1.0 sstables
into my environment in 1.2.16. Since the 1.0 days, the file format
has changes from this format.

Hi guys,
We're using expiring columns as a mean for locking. All of this
data should be completely ephemeral with only a 5 second ttl per
column. We're seeing some strangeness where our rows are getting
quite large with tombstones. We really don't need the commit log, nor
the sstables in our u
nning repair to ensure the data
is distributed correctly in the ring.

Hi all,
I have recently been trying to restore backups from a v1.0.x cluster we

Hi guys,
Now that dynamic composite have been introduced as part of cassandra
core, has any thought been given to implementing "order by" semantics to
secondary indexing? The dynamic composite allows asc/desc order sorting
of each component in the composite, allowing for mixed asc/desc order in
files after redefining the schema?

Hi all,
I seem to have backed myself into a corner and I cannot easily upgrade
from a custom 0.7.4 installation to the default 0.8.2. Any help I could
get would be greatly appreciated. Below is an outline of the problem.
Current installation:
0.7.4 with Ed Anuff's custom composite comparators.
It sure seems to think it's using OPP and not BOP...

Hi all,
I'm getting some strange invalid token errors. I'm on Cassandra 0.7.0.
Using the JMX console, each node has a valid token. Also, each node shows
as a live node in the cluster. Any ideas why I'm getting this error? I've
restarted the entire cluster and I can't seem to resolve the pro
We use Lucandra as well for searching for users, as well as
geo-encoding. It really works well except for numeric fields.

That bug may be a bit of an issue, but after they release 0.6.5 all the
Lucene functionality will be available to you.

Hi all,
I'm having a lot of problems getting Lucandra to correctly handle numeric
document fields. After examining the keys it has written to the CF, I
believe it may be an issue of column ordering by bytes. After dumping the
CF with the test data using sstable2json, the keys are in opposite o
I like both. Personally, I have switched from Hector to Pelops. Let me be
clear, this is not because Hector is not a good client. Ran has done an
excellent job with Hector, and it was what I initially used for my plugin.
I preferred Pelops for my Datanucleus plugin since it requires slightly

Correct Ran. It seems like the only way I'm going to get true mutations
in a single op is to use Cages. Thankfully a majority of our
application won't require it, just a few specialized components.

Hey guys,
I originally asked this on the Hector group, but no one was sure of the
answer. Can I get some feedback on this. I'd prefer to avoid having to use
something like Cages if I can for most of our use cases. Long term I can
see we'll need to use something like Cages, especially when it c
Hi all,
First off, thanks for putting out such a great product and documentation.
I had a node up and running on CentOs in 10 minutes, and had our C# app

Now that I have basic prototyping working, I have a few networking and data
