IN operator and Order By falls back to Scan

[shemekh]

Expected Behavior

I have a paging repository as follows:

public interface PagingMessageLogRepository extends PagingAndSortingRepository<MessageLog, MessageLogId> {
	Page<MessageLog> findByInstanceIdOrderByInsertedDateDesc(Long instanceId, Pageable pageable);
	Page<MessageLog> findByInstanceIdInOrderByInsertedDateDesc(List<Long> instanceId, Pageable pageable);
}

instanceId - Hash key
insertedDate - Range key

Problem is with the second method that uses IN operator.

Actual Behavior

First method works as expected and returns MessageLog objects with provided instanceId. Second method is not working properly and throws error. Surprisingly it falls back to Scan instead of performing Query. Thrown error is: Sorting not supported for scan expressions..

Steps to Reproduce the Problem

1. Self explanatory based on above sections.
