Cassandra doesn't load any keyspaces by default. You have to manually do it
once. Using loadSchemaFromYAML method exposed by JMX

Curious if anyone has done input from a cassandra super column? Any support
for this currently? Thanks
You can install cygwin in order to run mapred job locally on windows

We are putting together a patch for that. Also updating the unit test to
capture this case. It wasn't failing as a result of it being backwards.

This appears to be backwards.

Hey I'm testing a client on beta2 cassandra version 0.7.
TFramedTransport transport = new TFramedTransport(new
TSocket("my.ip", 9160));
Cassandra.Client client = new Cassandra.Client(new
TBinaryProtocol(transport));
transport.open();
System.out.println(client.descri
I didn't notice the number of hot CFs mentioned below. So with data in
them. We are sharing a cluster with others, so I'm trying to get an idea of
what overhead there is for empty CFs if any. What are internal caches?

Hey,
As I understand it writes go directly to the commit log. Once a threshold
has been reached the data is shipped to a memtable, and again to an sstable.
1. How many memtables are created when a flush happens from a commit log?
One per CF?
2. Is there any space associated with an empty memtab
Thanks Eric.

Hey
Is there a release date (or approximate date) for cassandra 0.6.4. We are
mainly concerned about the Cassandra-1042 patch. The reason we don't simply
apply the patch is because since we are shipping a product which interacts
with the cassandra server (and the patch is server side), the custo
