With Composite Column Name, you can even have column composed of sore
(int) and userid (uuid or whatever). Empty column value to avoid
repeating user UUID.

I was moving around some nodes in my cluster but when I get one node there
appears an error:
"Error during move: The data partitions for node [IP] have not been
determined"
How to solve this problem?

Hi all,
I've red all your messages concerning the top 10 ... any solution is possibile
but I still did not find the best one.
Using a composite Column Name as suggested would be smart cause it brings to a
sorted row where I can have my top-10 in any moment but it can slow down all
the platform
I have following CF
Read Count: 68844
Read Latency: 9.942 ms.
Write Count: 209712
Write Latency: 0.297 ms.
Pending Tasks: 0
Bloom Filter False Postives: 10
Bloom Filter False Ratio: 0.0
> Read Count: 68844
[snip]
> why reported bloom filter FP ratio is not counted like this
10/68844.0
> 0.00014525594096798558
Because the read count is total amount of reads to the CF, while the
bloom filter is per sstable. The number of individual reads to
sstables will be high
