Hi All, On each row I have a column which maintains the timestamp like "lastUpdated" etc. While inserting such row I want to make sure that the row should be only updated if the lastUpdated is older than the new one I am inserting. One way to do this is - Read the record first check the timestamp if newer is latest then update. Since I have higher volume of read and writes load. This additional read will add to it. Any alternative to achieve this? Thanks, Jay | |
