How can you make a paginated request (limit, offset, and sort_by) using dynamoDB? On mysql you can:
SELECT... LIMIT 10 OFFSET 1 order by created_date ASC
I'm trying this using nodejs, and in this case created_date
isn't the primary key, can I query using sort key created_date
?
This is my users
table
{
"user_id": "asa2311",
"created_date": "2019/01/18 15:05:59",
"status": "A",
"rab_item_id": "0",
"order_id": "1241241",
"description": "testajabroo",
"id": "e3f46600-1af7-11e9-ac22-8d3a3e79a693",
"title": "test"
},
{
"user_id": "asa2311",
"status_id": "D",
"created_date": "2019/01/18 14:17:46",
"order_id": "1241241",
"rab_item_id": "0",
"description": "testajabroo",
"id": "27b5b0d0-1af1-11e9-b843-77bf0166a09f",
"title": "test"
},
{
"user_id": "asa2311",
"created_date": "2019/01/18 15:05:35",
"status": "A",
"rab_item_id": "0",
"order_id": "1241241",
"description": "testajabroo",
"id": "d5879e70-1af7-11e9-8abb-0fa165e7ac53",
"title": "test"
}

Pagination in DynamoDB is handled by setting the ExclusiveStartKey
parameter to the LastEvaluatedKey
returned from the previous result. There is no way to start after a specific number of items like you can with OFFSET
in MySQL.
