DynamoDB QueryRequest不返回所有结果

Question

    val queryReq: com.amazonaws.services.dynamodbv2.model.QueryRequest = new com.amazonaws.services.dynamodbv2.model.QueryRequest(tableName)
                    .withIndexName(...)
                    .addKeyConditionsEntry(..., new com.amazonaws.services.dynamodbv2.model.Condition()
                                        .withAttributeValueList(Seq(new com.amazonaws.services.dynamodbv2.model.AttributeValue(...)):_*)
                                        .withComparisonOperator(...))
                    .addKeyConditionsEntry(..., new com.amazonaws.services.dynamodbv2.model.Condition()
                                        .withAttributeValueList(Seq(new com.amazonaws.services.dynamodbv2.model.AttributeValue().withN(...)):_*)
                                        .withComparisonOperator(...))
                    .withScanIndexForward(scanDirection)
                    .withLimit(5000000)

此查询的limit = 5000000，但仅返回了大约3000个结果。 DynamoDB在每个查询中返回多少数据有限吗？如果是这样，是否有一种干净的方法来克服这一限制？

我刚找到解决方案。所以我会回答自己的问题：
当GetLastEvaLeDKey（）不是空或空的时，我可以创建一个附加结果集的wir循环。
