Description

If you have rows that are densely populated (most versions have all the columns) and heavily versioned, and if you are doing things like checking difference between the versions, it would be really handy to be able to get all of the versions and data at once. This method would let you do that.

Map<long, Map<Text, byte[]>> getRowTimestampsWithColumns(Text row);
Map<long, Map<Text, byte[]>> getRowTimestampsWithColumns(Text row, Text[] columns);
Map<long, Map<Text, byte[]>> getRowTimestampsWithColumns(Text row, Text[] columns, long timestamp);
Map<long, Map<Text, byte[]>> getRowTimestampsWithColumns(Text row, Text[] columns, long timestamp, int numVersions);
