01-create-table.js

01-create-table.js 程序将创建一个表 (TryDaxTable)。本部分的其他 Node.js 程序都将依赖此表。

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)); } });
