1. On HBase reference guide section 6<http://hbase.apache.org/book.html#schema>, We know that rowkey design should not using Monotonically Increasing Row Keys/Timeseries Data ，but if we need a time stamp sort data or a top list data, how to design the row key?
2. If I want statistics users' login data. I need to get one day somebody logins details(on what time, client info, etc.), to design like this: rowkey column userid:date (fmt:2013-01-01) c:time (colum fmt c:12:38:56) value (client info) example, get 't1','zhouhh:2013-01-01' zhouhh:2013-01-01 column=c:12:38:56 value=2013-01-01 12:38:56:zhouhh zhouhh:2013-01-01 column=c:13:42:58 value=2013-01-01 13:42:58:zhouhh ... there will be a lot of column names,but it is efficient to get one user on one day login info. there are any problems? Thanks, Andy Zhou
