It's not. When slicing columns you can only return one contiguous range.

If this is still a test environment can you try to reproduce the fault ? Or
provide some more details on the sequence of events?
If you still have the logs around can you see if any ERROR level messages were
logged?

Hi,
AbstractHashedPartitioner defines a maximum of 2**127 hence an order of
(2**127)+1.
I'd say that tokens of such partitioners are intented to be distributed in
Z/(127), hence a maximum of (2**127)-1.
Could there be a mix up between maximum and order?
This is a detail but could someone

I'm preparing the test below. I've found a lot of information about

Thank you Aaron Guillermo,
I find composite columns very confusing :(
To reconfirm ,
1. we can only search for columns range with the first component on the
composite column.
2. After specifying a range for the first component, we cannot further filter
for the second component. I found
Hi,
Suppose I have a column family to associate a user to a dynamic list of items.
I want to store 5-10 key information about the item, no specific sorting
requirements are there.
I have two options
A) use composite columns
UserId1 : {
itemid1:Name = Betty Crocker,
itemid1:Descr = Cake
First is better choice, each filed can be updated separately(write only).
Second you have to take care json yourself (read first-modify-then write).

Perhaps the syntax u're using isn't correct? You should be getting the
same data on all the nodes irrespective of which node's CLI you use.
The replication factor is for redundancy to have copies of the data on
different nodes to help
Sadly, I don't think we can get much.
All I know about the repro is that it was around a node restart. I've
just tried that and everything's fine. I see now ERROR level messages in

Clearly, some other conditions are required but we don't know them as yet.

I can't really see why you need a SC here since
If you are starting out new use composite column names/values or you could
also use JSON style doc as a column value.

If consistency is top priority, you can ensure that a read will always reflect
the most recent write by using the following formula:
