Pseudo code : GregorianCalendar gc = new GregorianCalendar(); DateFormat df = new SimpleDateFormat( "yyyyMMddhhmm'); String reversekey = df.format(gc);
set mycolumnfamily['myrow']['mycolumn'] = 'myvalue'; set myreverseindex['$reversekey]['myrow'] = ''; Under rapid insertion this makes hot-spots. Not an easy way around that other then sharding the reverse index.
