How to get all fields present in aws-dynamoDB?

Question

I am using Node.js

var AWS = require('aws-sdk');

AWS.config.update({
  region: "region",
  endpoint: "https://dynamodb.region.amazonaws.com"
});
var dynamodb = new AWS.DynamoDB();
    var params = {
      TableName: "acc_new"
    };

    dynamodb.describeTable(params, function(err, data) {
        if (err) console.log(err, err.stack); // an error occurred
       else     console.log(JSON.stringify(data));
    });

Output :

{ AttributeDefinitions: [ { AttributeName: 'Id', AttributeType: 'S' } ],
  TableName: 'acc_new',
  KeySchema: [ { AttributeName: 'Id', KeyType: 'HASH' } ],
  ProvisionedThroughput: { ReadCapacityUnits: 5, WriteCapacityUnits: 5 } }

output consist of only key schemas(hash and range keys only) associated with the table, Not all the attributes. I want to fetch all attributes associated with data in the table.

Like:

 { AttributeName: 'AccountName', AttributeType: 'S' }
 { AttributeName: 'CreatedBy', AttributeType: 'S' }
 ...
 ...

Is there any way to get descriptions of a dynamoDb table with all of its data fields.

Answer 1

DynamoDB is a NoSQL database. While creating the table, it doesn't expect all the attributes to be defined in the table. Also, each item can have any number of non-key attributes. Only key attributes are common or mandatory across all the items in the table.

For the above mentioned reasons, the describe table can't provide all the attributes present in the table.
