It looks like versioningiterator gives me the past versions for a cell .... but I need to look across rows ..
I am inserting time series data for set of machines into accumulo and i am using a combo of machineid + timestamp as the row ID and metric as the cq. So for me to get the last time a metric has been inserted for an asset, i need to look across row IDs and get the last 5 rows that got inserted with that metric ...
