hbase

Hello i've just started exploring hbase

i've run 2 samples : SampleUploader from examples and PerformanceEvaluation as given in

hadoop wiki: http://wiki.apache.org/hadoop/Hbase/MapReduce

Well, my application involves updating huge amount of data once a day.. i need samples that store and retrieve rows based on timestamp and make an analysis over the data

could u please provide r poinnters as to how to continue as i dont find many tutorials on samples using TIMESTAMP

thank u a lot sammy
