01-create-table.js

El programa 01-create-table.js crea una tabla (TryDaxTable). Los demás programas de Node.js en esta sección dependerán de esta tabla.

const AmazonDaxClient = require("amazon-dax-client");
var AWS = require("aws-sdk");

var region = "us-west-2";

AWS.config.update({
  region: region,
});

var dynamodb = new AWS.DynamoDB(); //low-level client

var tableName = "TryDaxTable";

var params = {
  TableName: tableName,
  KeySchema: [
    { AttributeName: "pk", KeyType: "HASH" }, //Partition key
    { AttributeName: "sk", KeyType: "RANGE" }, //Sort key
  ],
  AttributeDefinitions: [
    { AttributeName: "pk", AttributeType: "N" },
    { AttributeName: "sk", AttributeType: "N" },
  ],
  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)
    );
  }
});
