Can we use DynamoDB Mapper for atomic counters(Java)?

Question

I was looking at DynamoDB documentation and googling, but I could not find any implementation of atomic counters using DynamoDB mapper.

Is this possible? Or only the low level API can be used for this?

Answer 1

With the Java API you should look at UpdateItemRequest with AttributeAction.ADD

The lower level api can also be used

Edit after comment..

I am not aware of that option. Perhaps you should edit your question and add the code you wished was available.

If you want a @DynamoDBAutoIncrementAttribute for an integer - there isn't one.
