I have a 'long' number that I get by using HTable.'incrementColumnValue'. This long is used as the qualifier id on a columnFamily.
However in my listings, I always want the latest number first (descending order basically). Currently I call the NavigableMap.descendingKeySet after I do the 'Get'. Is this the optimal way of doing it? Can I do something that can be faster? Especially if I start filtering out and getting only first 1000 etc then this wont work. How should I go about this? Change the key or is there something else I can do while creating the table, doing a Get etc? Thanks.
