Formatting DynamoDB data to normal JSON in API gateway - json

Question

just like the question asked here
I do a query or scan operation on dynamoDB using dynamoDB proxy service on AWS API Gateway to read data for the Client and I get DynamoDB formatted JSON data in reply.
Although I can use the "Method Response" to convert but when the Data is above 1000 records - I cannot handle it due to the limitation of foreach loop in Method Response.
Is there a flag or a setting somewhere in dynamodb or in api gateway such that I get normal json rather than the dynamoDB formatted JSON ?
DynamoDB Formatted JSON example
{
"videos": [
{
"file": {
"S": "file1.mp4"
},
"id": {
"S": "1"
},
"canvas": {
"S": "This is Canvas1"
}
},
{
"file": {
"S": "main.mp4"
},
"id": {
"S": "0"
},
"canvas": {
"S": "this is a canvas"
}
}
]
}
Normal Json example of the same
{
"videos": [
{
"file": "file1.mp4",
"id": "1",
"canvas": "This is Canvas1"
},
{
"file": main.mp4",
"id": "0",
"canvas": "this is a canvas"
}
]
}

Answer 1

Using an Integration Response mapper!
The mapper would probably look something like: (I'm using your provided response)
#set($inputRoot = $input.path('$'))
{
"videos": [
#foreach($elem in $inputRoot.Items)
{ "file": "$elem.file.S",
"id": "$elem.id.S",
"canvas": "$elem.canvas.S" }#if($foreach.hasNext), #end
#end
]
}
Please consult the linked documentation for more complete guidance on attaching AWS Services directly to API Gateway.

The possible solution for this is using a aws lambda to query/scan dynamoDb and reply back the domain object after converting it into a json using some json lib, like GSON or jackson.
If any one has knowledge about an alternate option - please do post here. Thanks
