Use SQL Database forrelational datarich query, sorting, filtering, multiple indexes

Use Table forkey-value pair tuples (e.g. game state)simple queries, basic or no filtering

SQL Database vs Table

Page 13: REST API Connected Apps Windows Store iOS Android Windows Phone 8 iOS Android HTML 5/JS

Table Storage with Custom APIs

exports.get = function (request, response) {

var azure = require('azure');

var tableService = azure.createTableService(‘session', '<your storage key>');

var query = azure.TableQuery.select().from(‘session').where(‘eventId eq ?‘, eventId);

tableService.queryEntities(query, function (error, todoitems) {

if (!error) {

response.send(200, todoitems);

} else { /* … */}

});

};

Working with images / blobs

Blob Storage

Mobile Service

4 1. Request a blob url2. Request a SAS token3. Send back a blob url4. Post a blob

Page 15: REST API Connected Apps Windows Store iOS Android Windows Phone 8 iOS Android HTML 5/JS

Blob Storage SAS

function insert(item, user, request) {

var azure = require('azure');

var blobService = azure.createBlobService('<account-name>', 'account-key>');

blobService.createContainerIfNotExists(item.containerName,

accessLevel, function (error) {

if (error) { return errorHandler(error); }

var sharedAccessPolicy = {Permissions : /* ... */, Expiry : /* ... */};

var sasQueryUrl = blobService.generateSharedAccessSignature(item.containerName,

item.resourceName, sharedAccessPolicy);

item.imageUri = sasQueryUrl.baseUrl + sasQueryUrl.path;

request.execute();

});

}

Page 16: REST API Connected Apps Windows Store iOS Android Windows Phone 8 iOS Android HTML 5/JS

DO NOT use compute intense scripts

function insert(item, user, request) {

//...

images.forEach(function (image) {

var png = easyimg.jpg2png(image, quality:10};

//...

}

Page 17: REST API Connected Apps Windows Store iOS Android Windows Phone 8 iOS Android HTML 5/JS

USE SQL where appropriate

postTable.where({id : commment.postId}).read( { success : pushToUsers });

//…

function pushToUsers(users) {

users.forEach(function (userId) {

channelTable.where(userId : userId).read({

success: function(channels) {

channels.forEach(function(channel) {

push.wns.sendToastText04(channel.uri, {text1: item.text } );

});

}

});

});

}

JOINS BETTER IN SQL

Page 18: REST API Connected Apps Windows Store iOS Android Windows Phone 8 iOS Android HTML 5/JS

USE SQL where appropriate

var sql = "SELECT channel FROM devices " +

"INNER JOIN posts ON devices.userId = posts.userId " +

"WHERE posts.id = ?";

mssql.query(sql, [comment.postId], {

success: function(channels) {

channels.forEach(function(channel) {

push.wns.sendToastText04(channel.uri, {text1: item.text } );

});

}

Page 19: REST API Connected Apps Windows Store iOS Android Windows Phone 8 iOS Android HTML 5/JS

AVOID doing 1000s requests in parallelvar sql = "SELECT channel FROM devices " +

"INNER JOIN users ON "; // TO DO: query users in SF

mssql.query(sql, [geofences.SF], {

success: function(channels) {

channels.forEach(function(channel) {

push.wns.sendToastText04(channel.uri,

{text1: “New Coffee” } );

});

}

• Use Notification Hubs

• Split the work into batches and process in the background

Page 20: REST API Connected Apps Windows Store iOS Android Windows Phone 8 iOS Android HTML 5/JS

AVOID client side JOINs

IEnumerable<Session> sessions;

Events = await App.MobileService.GetTable<Event>()

.Where(e => e.Start > DateTime.Now)

.ToEnumerableAsync();

foreach (var e in Events)

{

sessions = await App.MobileService

.GetTable<Session>()

.ToEnumerableAsync();

/*....*/

}

IEnumerable<Session> sessions;

Events = await App.MobileService

.GetTable<Session>()

.Where(e => s.Start > DateTime.Now)

.ToEnumerableAsync();

/*....*/

//JOIN in server scripts:

var sql = "SELECT * FROM sessions " +

"INNER JOIN events ON events.date > ?";

mssql.query(sql, [startDate], {

/*....*/

}

Add version to your Mobile Services clientpublic class VersioningHandler : DelegatingHandler{

protected override Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, CancellationToken

cancellationToken) {

request.RequestUri = new Uri(request.RequestUri.AbsoluteUri.ToString() + “?version=2.0");

return base.SendAsync(request, cancellationToken); }}

public static MobileServiceClient MobileService = new MobileServiceClient(

"https://eventbuddykg.azure-mobile.net/",

"lLsNsvgOmQBfUGOHgKkIgnFwblJpla63",

new VersioningHandler()

);

Page 31: REST API Connected Apps Windows Store iOS Android Windows Phone 8 iOS Android HTML 5/JS

Add version to your scripts

function insert(item, user, request) {

if (request.parameters.version < 2.0) {

session.room = 'Not entered';

}

request.execute({

success: function () {

if (request.parameters.version < 2.0) {

delete session.room;

}

request.respond();

}

});

Versioning Considerations
