Hi,
Wonder why this cap is in place? We are experimenting on some CF names with
UUIDs and hit this issue.

Sasha,
It depends on the way you implement I guess... Maybe twitter uses Solandra,
who's very good at indexing these in different ways but has the power of
Cassandra underneath...
If your doing your own impl of indexing be mindful that you can break the
sentence into four words and index or you i

Hi,
I try to add column families programatically and end up with 2 schema
versions in the Cassandra cluster. Using Cassandra 0.7.
Is there a way to bring this back to normal (to one schema version) through
the cli or through the API?

Hi everyone,
I add a column family dynamically and notice that when describe schema
versions return 2 values. Then it quickly changes back to 1. Sometimes this
stays at 2 and does not change. Then I cannot insert values to the created
column family, as it causes an exception.

Any idea whether the hive functionality will be merged to the Cassandra

Hi,
I'm trying to experiment with Hive using Data in Cassandra. Brisk looks
good, but I'm interested in running the map reduce jobs on HDFS not on CFS.
I'm taking a look at [1], but couldn't figure out how to run it with a
Cassandra cluster. I was wondering is there a simple word count example

Hi,
We use Cassandra in a way we always want to range slice queries. Because,
of the tendency to create hotspots with OrderedPartioner we decided to use
RandomPartitioner. Then we would use, a row as an index row, holding values
of the other row keys of the CF.
I feel this has become a burden and
Would really appreciate any help on this.

Hi,
I'd like to do $subject. Is there a way to do this?
I feel this should be possible by hashing the key and comparing the token of
each node. But I don't know the internals enough to know exactly?
This is to tell hadoop to fetch a record from a specific node. I'm customizing
the CFIF.

Hi everyone,
I noticed this line in the API docs,
The method is not O(1). It takes all the columns from disk to calculate the
answer. The only benefit of the method is that you do not need to pull all
the columns over Thrift interface to count them.
Does this mean if a row has a large number of c
The example works against the 7.0 branch, not against trunk.

Hi,
I have an already running system where I define a simple data flow (using a
simple custom data flow language) and configure jobs to run against stored
data. I use quartz to schedule and run these jobs and the data exists on
various data stores (mainly Cassandra but some data exists in RDBMS li

Hi everyone,
I'm trying to use Cassandra to replace a RDBMS.
My application handles domains. And, for every domain it creates a new DB
with a pre-defined set of tables.
After reading the documentation, I assume that this should be handled on
Cassandra by creating new key spaces.
Could I know if
