node.js - How to set on-demand capacity for a DynamoDB table using JavaScript SDK

Amazon DynamoDB has two read/write capacity modes for processing reads and writes on tables: On-demand Provisioned (default, free-tier eligible)

This is how I create provisioned table

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

AWS.config.update({
  region: "us-west-2",
  endpoint: "http://localhost:8000"
});

var dynamodb = new AWS.DynamoDB();

var params = {
    TableName : "Movies",
    KeySchema: [       
        { AttributeName: "year", KeyType: "HASH"},  //Partition key
        { AttributeName: "title", KeyType: "RANGE" }  //Sort key
    ],
    AttributeDefinitions: [       
        { AttributeName: "year", AttributeType: "N" },
        { AttributeName: "title", AttributeType: "S" }
    ],
    ProvisionedThroughput: {       
        ReadCapacityUnits: 10, 
        WriteCapacityUnits: 10
    }
};

dynamodb.createTable(params, function(err, data) {
    if (err) {
        console.error("Unable to create table. Error JSON:", JSON.stringify(err, null, 2));
    } else {
        console.log("Created table. Table description JSON:", JSON.stringify(data, null, 2));
    }
});

How I can set on-demand capacity for the table?

    You'll want to set the BillingMode as described in the AWS JavaScript SDK createTable docs. Add the following to your params:

    BillingMode: 'PAY_PER_REQUEST',
