For instance, I have an json array like:
[
{
color: "red",
value: "#f00"
},
{
color: "blue",
value: "#00f"
},
{
color: "cyan",
value: "#0ff"
}]
Seems the dynamoDB recommendation is to add a "key-name" to the array.
[
color1: {
color: "red",
value: "#f00"
},
color2: {
color: "blue",
value: "#00f"
},
color3: {
color: "cyan",
value: "#0ff"
}]
Is there a different way to add an json array into DynamoDB?
Couple of clarifications first:
DynamoDB supports List data type natively. Check here.
If you are using the DynamoDBMapper library in Java, you can do something like:
@DynamoDBTable(tableName="...")
public class ... { // POJO
private List<Color> colors;
... // Getters and setters
@DynamoDBDocument
public static class Color {
private String name;
private String value;
... // Getters and setters
}
}
If you are using AWS-SDK Java, then you can marshall your complex object to store it as JSON in DynamoDB. Please refer the below blog for more details. Specifically, I am referring to:-
@DynamoDBMarshalling (marshallerClass = PhoneNumberMarshaller.class)
class PhoneNumberJSONMarshaller extends JsonMarshaller<PhoneNumber>
{ }
