Paging & Sorting

Uses general find paging, reactive PageStream, aggregation pages, and ordered SortSpec appropriately.

General find paging

java

pageNumber is 0-based. A nested builder in the form of paging().pageNumber(...).pageSize(...).and() can also be used.

PageStream

java

대량 처리에서 data를 즉시 List로 모으고 싶지 않다면 PageStream을 사용합니다. 필요하면 collectToPageResult()로 PageResult<T>로 변환할 수 있습니다.

Aggregation paging

java

executeAggregation()은 reactive page data를 최종 List로 collect해 PageResult<T>를 만듭니다. stream 상태가 중요하면 executeAggregationPageStream()을 사용합니다.

SortSpec

java

The sort key maintains the order in which it was added. Dynamic direction can use sort.of(direction, field) and Driver-native sort can be mixed with driver(Bson).

For stable pagination, use a unique secondary sort.

For lists with many identical score/date values, adding a stable and unique field like _id at the end can reduce page boundary issues.
