You have the keys for both tables, is there any reason you can't do a get, local append, put? If you do it in batch, then running a reduce job that collects all of the keys for a given value would be fairly efficient.

Do we have any API which can append text values or row Ids to a cell. I want to do a control break report and want to append row Ids to a cell value... here is an example. TableMain row1 : user1 row2: user1 row3 : user2 row4 : user3 reverse lookup. TableRLookup. user1 : row1,row2 user2: row3 user3: row4. now I get some more data. row5 : user4 row6 : user1 row7 : user2 row8 : user3 now I want my lookup to get updated incrementally, not the entire run. TableRLookup. user1 : row1,row2,row6 user2: row3,row7 user3: row4.row8 user4: row5 my rowIds are String., how can we do this without rebuilding the entire reverse lookup time from ground up. thanks, Vishal Kapoor
