> I have been looking for showing rows and paging through rows. Finally I write this extension to cassandra-cli tool. 
> Let's assume that we have the following data in column family named 'CF1':
> =========================
> Row 1:
> key: fdu1, name: 'Frank Du', city: 'NYC'
> Row 2:
> key: fdu2, name: 'Jonathan Ellis'
> Row 3:
> key: fdu3, name: 'Eric Evans'
> Syntax:
> =========================
> LIST keyRangeExpression limitClause?
> keyRangeExpression:
>         columnFamilyName[ startKey : endKey ]  ( [ 'superCoumnName' ] )? 
> limitClause: 
>         LIMIT count (OFFSET offset)? 
>         \| LIMIT offset, count
> The limit clause is the same with MySql.
> Examples:
> =========================
> // list all the 3 rows in CF1
> list CF1[ '' : '' ]    
> // list all rows, offset from index 1. So it will show 2 rows
> list CF1[ '' : '' ] limit 1, 10    
>  // show the rows 'fdu2' and 'fdu3'
> list CF1[ 'fdu2' : '' ] limit 10
