Retrieving all columns from a result

Hi all,

I am trying to get all columns from a certain number of records I am
fetching. I am using the RangeSlicesQuery to achieve this, but it
forces me to set how many columns I want to be retrieved.


RangeSlicesQuery<UUID, String, String> rangeSlicesQuery = HFactory
                .createRangeSlicesQuery(keyspace, uuidSerializer,
stringSerializer, stringSerializer)
                .setColumnFamily("columnFamily1")
                .setRowCount(pCount)
                .setRange(null, null, false, 100);

I was wondering if there is something like an example on how to use
ColumnSliceIterator on this type of query.
Thanks in advance!

Thanks Vivek that worked!
But I can't use a ColumnSliceIterator with this type of query?

Try this, if it works for you.
