I wonder if that might be related to this:

We switched from a Concurrent structure to LinkedBlockingQueue in 0.6.

We are testing 0.6.0, compares with 0.5.1, and it seems:
1. 0.6.0 need more memory/heap.
2. after inserted billions of columns, tens-million of keys, the inseting
operation become very slow and jamed.
Exceptions TimeoutException and UnavailableException are throwed sometimes.

you mean all the columns in a row, or all the rows in a columnfamily?
the first you can do with get_slice, the 2nd you can do with get_range_slices.

Hi Mason,
Honestly, I am beginner user in Cassandra. I rather confused to follow
this database. I ask to the forum about the reason twitter.com to use
Cassandra
because I want to know the basic reason why we choose Cassandra instead of
RDBMS or OODBMS. Twitter.com is only a study case.

Hello Jonathan,
I supposed the same, that's why I tried the count_columns() call, but when I
try it with some big SCF, I get the same error message:
Thrift::TransportException: Socket: Timed out reading 4096 bytes from
127.0.0.1:9160
Should I use count_columns() or is there any other way to kn

I had a single-node instance (0.5) that has some data (1 SCF has 1 key and
about 500k columns). I upgraded the node to 0.6 release yesterday and added

Hi,
Lets say I wanted to store 2 dimensional data in the database, each object
has a X and Y location in a very large space.
I want to query Cassandra for all objects within a rectangle.
My understanding is that my objects can only be indexed by one key, one key
for each single object in my tabl
