How set update expression on field for dynamodb?

Question

Loot at the answer hibernate supports to set custome sql expression for class fields. Is there something similar for dynamodb mapping?

Answer 1

I am not aware of any if there is an option. The closest I got to was using this library

https://github.com/derjust/spring-data-dynamodb

and the wiki for that

https://github.com/derjust/spring-data-dynamodb/wiki/Supported-Spring-Data-Comparison-Operators

and example of how I have used it is

someRepository.queryBySomeKeyAndUpdateNumberGreaterThan(key, randomNumber)
