Paging collections using streams

/ Common cases of too much set data , If you cycle or process directly , The server may not be able to stand it , Now , We can batch the total data set , Then the batch data is processed in a single batch , So as to improve the performance of the server

// Paging the collection
Integer pageSize = 10;
List<List> trackPointCollect = IntStream.range(0, (trackPointList.size() + pageSize - 1) / pageSize)
.map(pageNum -> pageNum * pageSize)
.parallel()
.mapToObj(i -> trackPointList.stream().skip(i).limit(pageSize).collect(Collectors.toList()))
.collect(Collectors.toList());
