Yes you can , you just have to use CQL3 and 1.1.10 onward cassandra
supports CQL3. Just you have to aware of the fact that a column family
that contains a counter column can only contain counters. In other other
words either all the columns of the column family excluding KEY have the
counter type
And what syntax would be, if it's possible?Thanks.
The key cache and row cache graphs in OpsCenter broke when the caches moved
from per column family to global. The next release of OpsCenter should fix
that.

I also found that "nodetool info" gives some information as well. For

Key Cache: size 104857584 (bytes), capacity 104857584 (bytes), 15085408

You can slice the "key1" row to get the columns that have "xyz" as the value
for the first component in the column name. Check the docs in your client for
how to do that.
Hope that helps.

whether that is order preserving or not?
I couldn't be sure of a query that was based on order of the rows in the

Did you look at get_range_slices? Once you get the columns from super

What command are you running to get this error ?

There isn't currently, but perhaps you could contribute one :). If you take a

There isn't currently, but perhaps you could contribute one :). If you take a
look at the sh script in the bin directory of the word count example, it
shouldn't be terribly difficult to mimic the behavior. It's mostly just
setting up the classpath and executing the Java class with some argumen
i don't know how to set the command line
is there a word_count.bat ? like the word_count in the bin on linux?

Can I use tokens? I read that a KeyRange with tokens is end-inclusive, and
can wrap, so I can just give the local node's token as
I cam through the same problem. I have set the end key same as start key, it
