03-getitem-test.js

The 03-getitem-test.js program performs GetItem operations on TryDaxTable.

const AmazonDaxClient = require("amazon-dax-client"); var AWS = require("aws-sdk"); var region = "us-west-2"; AWS.config.update({ region: region, }); var ddbClient = new AWS.DynamoDB.DocumentClient(); var daxClient = null; if (process.argv.length > 2) { var dax = new AmazonDaxClient({ endpoints: [process.argv[2]], region: region, }); daxClient = new AWS.DynamoDB.DocumentClient({ service: dax }); } var client = daxClient != null ? daxClient : ddbClient; var tableName = "TryDaxTable"; var pk = 1; var sk = 10; var iterations = 5; for (var i = 0; i < iterations; i++) { var startTime = new Date().getTime(); for (var ipk = 1; ipk <= pk; ipk++) { for (var isk = 1; isk <= sk; isk++) { var params = { TableName: tableName, Key: { pk: ipk, sk: isk, }, }; client.get(params, function (err, data) { if (err) { console.error( "Unable to read item. Error JSON:", JSON.stringify(err, null, 2) ); } else { // GetItem succeeded } }); } } var endTime = new Date().getTime(); console.log( "\tTotal time: ", endTime - startTime, "ms - Avg time: ", (endTime - startTime) / iterations, "ms" ); }
