Cassandra中的分页与Spring数据

Question

I'm trying to get paginated results in cassandra using springboot, but I'm not getting desired results. Here is my code.

  Slice<User> usersByNameSlice =
      userRepository.findAll(CassandraPageRequest.first(10));
  while (usersByNameSlice .hasNext()) {
//.. process
    usersByNameSlice = userRepository.findAll(usersByNameSlice.nextPageable());
  }

I have around 35 users. This while loop works 3 times covering 30 users, but it comes out of the while loop after 30. How to solve this problem?

Answer 1

I think that you need to change the condition of the while loop to usersByNameSlice.hasContent() to check if there is content in the slice at all.

(Or maybe to combine it with check isPaged() even - because nextPageable on the last page will return unpaged state).
